I have been on the implant for 1 week and 2 days, after being taken off the mini pill which I was on for 4 years due to being forgetful for the past 4 months and having a imbalance in my hormones. I have also recently come out of hospital duw to server migraine attacks. But as of yesterday I have experienced such an uncomfortable cramping as soon as me and my partner finish having intercourse. As soon as my partner pulls out I am experiencing painful cramps in my lower stomach and thighs. This passes after about 10 minutes but I find the only way to help it is to focus on my breathing and rocking back and forth. A few years ago I was checked for cystsand any other abnormalities and underwent a ultra sound scan which came back clear. I am terrified because I do worry if this could be a sign of infertility which wouls break my heart as I am 20 years old and would lovw to have kids one day. Any advice is good advice at the moment.
