Can someone help me out?

I messed up and forgot to take my birth control 4 days in a row the week after my last period ended. A week before my next period was supposed to start (Wednesday) my boobs started to really hurt and I was getting waves of nausea. I thought, ok I’m pregnant. (Actually kind of excited) I took two pregnancy test both of which were negative BUT with my first pregnancy I didn’t get a positive until a week after my missed period. (Which would be this coming Wednesday) anyway this morning I started bleeding, it’s light, but now I’m super confused. Could I still be pregnant? Tender breasts and nausea have never ever happened as a sign of PMS for me. Thanks for reading, just trying to ease my mind, my birthday is tomorrow so I’m going to test again in the morning. Any advice or opinions are appreciated.
