Is my gf pregnant?

Patient: 3 months ago me and my gf had intercorse. a week after we did she had her period normal. 3 months later she had it again difference is the bleeding lasted 2 days and she passed 2 dark dark red blood clots. she does not have morning sickness and her breasts have not gotten larger but she has some other signs of it but she sometimes gets those anyways. she also takes birth control regularly

Doctor:
