I’m worried please help

So my boyfriend and I had protected sex in January 22 however, the condom broke. He said he didnt ejaculate inside of me but there’s was some white drops on his penis. I freaked out and decided to take a plan B. A few days later due to the Plan B I started my period early and lasted 5 days. Now since yesterday out of nowhere I’ve been experiencing some bleeding not enough to fill a pad tho. When I wipe there’s some light red/pink color and now I went to the bathroom and some drops of blood came down too. What could it be? I’m scared to be pregnant🤦🏻‍♀️
