I had my period before I got the nexplanon remove.. Then after the remover I been having unprotected sex since then with my partner and every time he comes in me... I ended go seeing a doctor they told me sometime it can happen right away r take months... I'm just worry bout that one... I had my period on May 21 and it lasted 4 days but wen I was on the birth control it was longer then that... So after I was off my period me and my boyfriend had sex again and again without protection... So I was wondering how long before u can conceive another child!!!
