How Soon Can One Conceive After An Ectopic Pregnancy?

Hi, I ve just recently had an Ectopic pregnancy around April 4th, 2017.. my boyfriend and I were devastated and I ve been trying to schedule appointments, but Yale is so busy I miss and then they re always booked! Mind you me and my boyfriend have been having a lot of unprotected sex and he has been ejactulating inside of me and I m slowly starting to feel stomach pain and Anal pain , with no cause of anal sex. My period has came back on my normal cycle and last time it has come was May 9 and around the days that I would ovulate if I hadn t gotten pregnant I ve been having a lot of unprotected sex, will it work on the days I was ovulating?? Because I know the doctors said wait four months but I don t know if I should go to the e.r. Because it might be happening again and it s my last tube, but I thought after you have an ectopic pregnancy your body won t allow you to get pregnant until 4 months but I need some help thank you.
