I loved the copper coil however it caused very heavy and long periods and I had to get it out after 5 months due to anaemia. I also have pmdd so I wanted to try something hormonal to ease this

Before having the copper coil, I’d tried all other forms of contraceptives. I got to a point where I felt, even though the copper coil would cause more heavier and painful periods, it was non hormonal so thought it was my old option (hormones really don’t suit me) The insertion was pretty bad I won’t lie but when it’s done it’s done! I never could feel my threads and my periods went from 5 days to 10 days. I went from being someone with light periods to unbelievably heavy; to the point I was wearing period knickers with two overlapped night pads for two of the days. The nurses said after 6 months my body would adjust and the bleeding would settle down. They started me on TXA as my ferretin and iron became low. To cut a long story short the bleeding never settled and I was still having ten day long periods. It was a horrible 12 months as I felt the majority of the time I was on a period and doing daily tasks or working proved very very hard some days. I became anaemic and would spend a lot of money on supplements alongside the prescribed iron. The anaemic led to a lower moon, zero sex drive, ravinous appetite and tiredness. I know they say research shows a small percentage gain weight on it and I was one of them. But they always like to say it’s others things like lifestyle. For me I was certain it was the coil due to the anaemia it causes. I’m 155cm and weigh 8 stone 3. I’ve always been that weight and I go to the gym 3-5 days a week, probably twice a week since the coil. I gained a stone in that year.

Brain fog ,Acne , weight gain , tender and painful breasts all the time as a result , extremely heavy periods, although it's non hormonal doesn't mean no side effects , be careful when considering " non hormonal contraception"

First 3 weeks were fine, I spent first 3 days filled with rage and nausea and a few headaches but fine. First expected period rolled around at 3 weeks in and didn't stop, like at all (day 77 as I write this). About 6 weeks in my mood crashed. As someone who has previously had mental health problems, I was incredibly apprehensive about going on any kind of hormonal birth control because I was scared of side effects. But in order to get my tubes tied, my doctors wanted to see me try this first and everyone reassured me that I was just being paranoid and it wouldn't be as bad as I imagined. Unfortunately it was worse than I imagined. I spent 4 weeks getting progressively more suicidal until I finally went to the doctors (which was its own story) but had to take three Valium a day in order to function and go to work. At the time of writing, I'm 2 weeks out of the 12-week expected window, still bleeding and still suffering mentally but less so and more manageably. This experience has put me off trying any other form of birth control. I had done this to try and reduce PMS symptoms and wish I never had. I was also recommended the mirena coil but didn't like the idea of having to have it inserted or removed if things went wrong/justify myself to a doctor

I went on the depo injection due to the mini pill making my IBS constipation symptoms worse and the doctor saying this would be better. For first 6 months, no side effects. It did level out my moods and constipation, but it gave me vaginal dryness and a loss of sex drive after 9 months of being on it.

I got with a new partner a few years back and gave this ago as I wanted something I didn’t need to remember to take. I gained weight fast, I had mood changes, my skin broke out badly, my periods were heavier than before. I only ever had one injection then stopped as I no longer needed it and I didn’t like how it made me feel. Unfortunately I had a rare side effect where it stopped my periods/ovulation all together for 12 months I was referred to gynaecology at 6 months and luckily after all the scans everything was normal and by month 12 my cycle returned without needing to be medically induced. This is not a horror story but important that you could react the same or if you are reacting the same please get referred to gynaecology and hopefully your periods will return 🤍

Having used both Depot and Sanaya Press, these are the best method of contraception. No side effect and a huge positive: no periods.

I would have rated this 5 stars last year. I used to be on the depo jab that had to be done at the doctors but I work 12 hour shifts meaning it was a struggle to attended every 12 weeks. So I was over the moon when I found out about sayana press that I could do myself. I usually do the injection around 11 weeks but the last 3 times I get to 10 weeks and get crippling period pain that completely debilitates me. Even after I’ve done the injection this will continue for about a week afterwards. I’ve never experienced child birth but the pain is horrendous. It will wake me up in the middle of the night, happen at work and is just completely random spouts of unbearable pain until at whatever point doesn’t happen again until I am next at the 10 week mark. I’ve recently learned that it’s a lower strength to Depo-Provera and maybe that’s why however I’m confused as to why it’s only started happening. My gp surgery is useless and it the whole process of going back to having the higher strength at the surgery is going to take some time but being able to do it at home is not worth this horrendous ordeal. I would not recommend switching

Great if you’re looking to prevent pregnancy with less admin. Having the year’s supply ant home and not needing to see a doctor every few months was handy. Stopped my periods aside from some very minimal spotting and my skin was great - I barely had any spots over the years I was on it. I did feel like I was quite numb emotions wise. I didn’t experience mood swings but it was alarming that I often didn’t really feel anything! My libido was extremely low too.
