Somebody help !

So oct 20 my bf came over .. he had already released prior to why I think I may be pregnant .. so we never actually had sex and in fact i am still a virgin .. but without protection , he placed his penis on my vaginal opening I'm guessing to see if I was ready , but I wasn't , and he stopped . Now on the 9th of November, i was using the bathroom when I went to wipe I noticed some pink discharge , I was getting nervous because I was thinking it was implantation bleeding. It then later became heavier and when this period started my obgyn prescribed me the pill form of birth control to help control my horrible pms , cramps and heavy bleeding , so I took it because I figured it was my cycle .It has been maybe a month and 5 days .. and my stomach is gurgling NONSTOP , I wake up in the mornings with aches in my lower stomach , I can't tell if my nipples and the skin around are darkening because they are naturally dark , but now my nipples are squishy . Everytime I press on my stomach it's hard and bubbling. Somebody help me ! And I'm really gassy and tend to poop ally more often
