hi, i had the implanon removed 8 days ago after having it in 3 and half years, it was overdue in coming out, i had unprotected sex that night and 3 times since as we were trying for baby number 2. the day after i had it taken out i started getting horrible sharp shooting pains up my down beloew bits and in my lower stomach, then today ive had some brown discharge. i did a pregnancy test 5 days agowhich was negative, does anyone know what these pains are? im really worried about it and am concerned i have had a miscarriage, thankyou.
