Copper coil (IUD)  

I got the copper IUD after 4 years of different hormonal pills as wanted to stop being on hormones. The fitting procedure went well, the doctor was reassuring and I had local anaesthetic so it was only a little uncomfortable. However the cramps afterwards were horrific - I was on the floor in tears with how much pain I was in. Painkillers and heat pads did nothing. This lasted a couple days then thing started to settle down until the cramps turned into a stabbing pain. Returned to the doctors, they initially said my symptoms were normal then checked my vitals before diagnosing me with a pelvic infection or Pelvic Inflammatory Disease (PID). I was on 2 antibiotics for a fortnight. The pain lingered but gradually got better after a month. I have just finished my second period off the pill. My period returned after 35 days of stopping the pill which was my old usual cycle. My period isn’t any longer than it used to be but I’d say it’s a bit heavier and more painful but definitely manageable. My moods have been so much better and predictable. My skin has gotten slightly worse as expected coming off the combined pill which helped my skin, but flare ups match up to my period so I don’t mind. I got the 10 year IUD but I don’t think I’d get another due to the worry of getting another infection but I am happy with it at last.

Copper coil (IUD)  

The IUD fitting itself was less bad than I expected, uncomfortable and a bit painful but not worse than period cramps. However, about half an hour or so after, I got quite intense cramping pain and almost fainted from it on the way home. The post-insertion pain settled after a few days. With the IUD, my periods were quite a bit heavier than before but this improved a bit after 6 months or so. With the IUD, I also got spotting between periods for a few days each month (possibly related to ovulation). Also, since having the IUD fitted, I started getting recurring sharp stabbing pain, always in the same spot on the right side (roughly where my right ovaries are). This pain was worst during my period, sometimes making me feel close to passing out even though I was taking the maximum daily dose of ibuprofen (I later switched to mefenamic acid but that was not much better), and it was much worse than any period cramps I had ever had and felt more like someone is stabbing me than like a cramp. I also had this same right-sided stabbing pain randomly throughout my cycle. Moreover, I also started getting cramping pain during exercise (running) after I got the IUD. The right sided stabbing pain and the cramps during exercise maybe improved slightly over time, but were still bothering me quite a lot after 9 months of having the IUD. I had several checks done to make sure the IUD was still in the right place and to exclude any underlying disease that could be causing the pain, but nothing abnormal was found that would cause pain like this. The doctor said that they could not exclude that the pain might be from a hormonal condition (like endometriosis) that was masked by the hormonal contraception (progesterone only pill) that I was on before I got the IUD. In the end, I decided to have the IUD removed to see if that would get rid of the pain, both because I felt that the pain was not something I was happy to tolerate indefinitely, and because I thought it would be important to know if I have something like endometriosis and this is what is causing the pain, because in that case I would have considered going back on hormonal contraception to slow it's progression (I wasn't happy with the side effects I got from two different combined pills and three different progesterone only pills, which is why I switched to the copper IUD, so I didn't want to switch back to hormonal contraception unless absolutely necessary). After I had the IUD removed, the right sided stabbing pain immediately went away completely, but I got the cramping pain during running once since - it hasn't been long since I had the IUD removed so I am hoping that this will eventually disappear too.

Copper coil (IUD)  

The copper IUD was great, I had it fitted and then didn't have to worry about contraception. However, the initial insertion was painful and it did make my periods more heavy and painful. I had the coil replaced after 5 years but this coil came out on its own. I do use a menstrual cup and the coil came out in the cup, so this could have been down to user error on my part.

I had no problems while using noristerate but I would get annoyed sometimes because I would experience spotting for 2 weeks before my next injection. I had little to no menstrual cycle.

Depo-Provera injection  

All women should really do the research before starting this medication. I have read quite a few stories online of women who have felt the same. I have basically felt like a completely different person. I am near on the end of one injection and I will not be going back for another. It’s absolutely ruined my relationship with my partner. I’ve been absolutely horrible to him and it’s only now I’m starting to realise just what this injection did to me. Thank goodness he’s so understanding and helped me through it because I was literally horrendous. Literally a few days after I had it I was a different person, I hated him. Everything he done annoyed me, I was rude and hurtful and I couldn’t control it. I would snap in and out of moods so badly that we named the other “person” Patrica. He was constantly walking on egg shells as he never knew which version he would get. I am so upset that I have felt this way in the last few months. So much so I was having suicidal thoughts. I pray that anyone doesn’t risk it because it’s been 3 months of hell for us.

Depo-Provera injection  

This has been great for me helped regulate my moods no longer huge crashes i get around periods. Also it has completely stopped my periods which were heavy and painful, I get the occasional period pain leading up to when my injection is due but they are very very mild and don’t really effect me.

Sayana Press injection  

Used for over 10 years, completely stopped my periods which was fantastic. The devices became harder and harder to use, needing a lot of force to inject so I ended up turning myself into a pin cushion & wasting a few, which made reordering a faff. Don’t think I gained weight and if anything my skin improved (but that could just be normal from teenage to late 20s). The only negative I noticed was decreased sex drive - but it didn’t totally go so not a massive issue for me.

Sayana Press injection  

I was on this injection for 2 years, the whole process put me off . when i started the injection i had a period of 16 days (over two weeks) and it was so heavy, months went on and my periods stopped all together, i didn’t have a period for minus 2 years , i’m now on the combined pill but i did receive higher anxiety and depression towards taking it for ages, the doctor offered me antidepressants but i didn’t want to be taking them as i am a quite smily happy person but i literally lost all my energy and motivation to do anything.
