Stoped birthcontrol early, Could I be Pregnant? If not when should I be ovulating?

ok so my reson for consen also is that, My boy friend and I had a threesome with one of his friends on the 15th. He never came in side of me.He with drew in plenty of time. unlike my boyfriend that always does.And me and the bf have sex everyday multible times a day. I didnt want to do this because I knew that I was not on bc. I took a hpt today and there was a very faint blue line? if I am pregnant what are the chances of this baby being this other guy? Also If I am testing Positive this early does that mean I may be farther along. how long after u consieve can you get a positive test. Please help me figure this out. I truly belive that it would be my bf but I need a way to reassure him

well day 14 would be today but I feel like I am already having early symptoms. I have been supper bloated and my boobs are really sore. I am thinking that I have ovulated really early. when I was pregnant with my 1st I knew I was pregnant a week before my period was due, I took a test and it was positive! with my second pregnancy (ended in a miscarrage) was the exact same way I tested a week before my period and I was positive, and I new it. I really feel like I am already and I should start my period on the 4th I took a test on wednesday the 19th because of how i have been feeling I knew that it would be way too early for it to come out positive almost 2weeks before my period is due. But I think that I am going to test again this wensday. I dont know Maybe I naturally ovulate earlyer then most people and that is why I tend to test positive a whole week before my period is due? what do you think?

I thought that I was supposed to get an ansewer in 24 hrs?

please help me!
