TooMuch Infoo

So me and my boyfriend have been dating for almost 2 years and we have been having unprotected sex since our second date ( please don’t judge!) And he stopped calling out after 11 months. I haven’t gotten pregnant and it’s not that we necessarily trying but it’s kind of freaking me out making me think I have a fertility issues. Any suggestions? I am 22 and very Concerned. Also I tried birth-control is to ensure that I wouldn’t get pregnant but the two or three times that I did try it I reacted to them horribly and ended up in the hospital every single time. Any suggestions for a potential birth control?
