I have the implant in about a month ago, before the implant I had unprotected sex couple times using pull out (which I no isn't great) and I had unprotected sex again once I had implant as I thought it was ok. I feel sick and have felt movements in stomach and cramps, now have spotting and back ache? Before I had horrendous periods I either had nothing or really heavy flow that didn't stop for weeks I've never had spotting. It was only that someone made a comment saying " sure your not pregnant" so now I'm confused rang the clinic who fitted it. They said that I should've been given pregnancy test before fitting and advised to used condoms for at least first week. I wasn't advised this or given pregnancy test. the receptionist on phone said she can't advise me what's best and implants have lots of side affects so could be anything? What do u guys think? Has anyone got pregnant on the implant? I'm away with extended family and we're living in each others ears so don't have the opportunity to go and buy a test right now but will get to it as soon as I can..
