Is it to early??

Troy • 23 years old
Okay so this is the boyfriend and I had unprotected sex (as always) during my fertile window it was 33% risk of pregnancy. Well I had to quit my birth control due to it making me really sick. I told him this and he still released all his babies inside of me. Now 6 days after, I have this pressure in my pelvic area specially after sex..I'm  having constipation and really bad gas (sorry might be tmi) anyways I just really don't know could I be experiencing symptoms of conception or what??? We weren't  trying to conceive however we weren't really not trying too so if we do get pregnant we will be happy if not we will be happy! What do you guys think????
