Help!?!?

Okay, I'm on the pill and have been for 6 months. I take them very regularly and have only taken 2 late (just by an hour or two) this month. My boyfriend and I always use a condom when we have sex. He never finishes in me even with the condom on. He'll put it in a few times without the condom on but he wipes off precum beforehand. I am the kind of person that it's not abnormal for me to get nauseous (I'm a very anxious person 😂). We did it the other day and I started bleeding and bled for like two days like a period. It was 3 days before I was supposed to start my sugar pills. I'm on my second day of sugar pills now and I have not started my period. My body is very weird and still does not want to get my period every month because I used to get it every 2 or 3 months before the pills.  Is there any possibility that I could be pregnant or am I just worried over nothing?
