Mirena coil  

Had the Mirena coil for 4 years. Insertion wasn’t a fun experience but only cramped for a few days. A bit of spotting for first few months but reduced to nothing for the next 4 years. Very happy with it, only getting removed to get pregnant.

Benilexa coil  

I was told to take painkillers (paracetamol & ibuprofen) before the procedure which I did. For the procedure I had two lovely ladies who were supportive and talked me through all of the steps. I was offered pain relief including gas and air, so all of that was great. What I didn’t realise was the “bad period cramps” you are warned about were actually more like mild contractions, and having had a traumatic miscarriage a few years ago. The coil fitting unfortunately ended up triggering this trauma along with my anxiety, when I spoke to my GP they mentioned it was PTSD and that this can happen after a coil fitting. Afterwards the coil felt really uncomfortable for about 4 weeks where I could feel it inside me all the time and sometime it felt like it was scratching around in there! Also certain exercise & stretches were uncomfortable & often aggravated it leaving me in pain. My hormones were also all over the place on week 3 but that passed fairly quickly. I’ve had great support from the clinic and was referred to have an ultrasound to confirm it was in the correct place. On a more positive note I’ve only had one heavy bleed a week after it’d been fitted and no further bleeds and so far only spotting once. It’s now 11 months later and things have settled, so this is now working for me which is a relief.

Mirena coil  

Had Mirena fitted to manage endometriosis after a laparoscopy. The period cramps felt worse than when I was on the contraceptive pill before the surgery. Also struggled with depression and low energy. Acne was about the same as before I started the contraceptive pill.

Noristerat injection  

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.
