Pregnant maybe?!?! Confused

So I've been feeling kind of sick lately neve felt this way before, stomach ache , no appetite, tummy is feeling really weird plus my discharge is really creamy and kinda thick I guess. I've been really horny lately, plus the last time I had sex was with my ex and he said in the midst of sex he was coming and I pulled him out but there wasn't any sperm, so I'm kind worried because I was taking the pill but I missed two pills days prior to that night. We just broke up three or fours days after that and I really just am afraid ladies can you tell me anything?
