Hey, I have been on the implant for 5 years. Before this I was on the pill for 5years. I had the implant removed almost three weeks ago and we have decided to non officially start trying to conceive. However I have read mixed things about fertility returning to normal straight away and others stating this can take 3-18months. I am just wondering if anyone can give me any advice? We had unprotected sex two weeks ago and the last few days I have had awful lower back pain and cramps. There is no sign of blood or spotting. My breasts have been a little tender and nipples are very sensitive than usual. I am confused because everytime I look online for advice it mentions everything around my period or after missed periods. Problem is.. I don’t know when I would be due on this as I have not had a period in so long!! When I had the implant in I would not have a period until the last year which would end up being 3-4 times during the year. Please help.
