I was on the sayanna press injection for 3 years. My periods started off a little irregular for the first couple of months and then stopped completely, which was a blessing as they have always been heavy and painful! Would start to get slight cramps in the week before the injection was due but otherwise, it seemed to suit me quite well. I'm a healthcare professional so injecting myself didn't bother me at all! I gained a little weight whilst using it but I am overweight anyway so unsure if I can attribute this to the injection!

I began using the Depo as it was recommended by a nurse in my GP clinic. During the first 6 months the only noticeable side effect was the decreased sex drive. After my 3rd injection, I began having serious pain when trying to have sex. Due to this pain I booked an appointment with my GP to get swabs done to check for any infections. They completed swabs and no infection was found, I was told it was most likely just dryness. Therefore I stopped having the depo and started the pill again as I had no issues with the pill. I was on the pill for a month and has really bad head aches so decided to come off contraception completely. After coming off the depo it took 6 months for me to be able to have sex again due to the dryness.
