I missed my period about 4 days ago my boyfriend

Patient: I missed my period about 4 days ago my boyfriend told me he ejaculated in me during inter course and I was having symptoms which I did a lot of research on and now I’m bleeding a bright bright red blood on my pad and pink when I wipe and I’m nervous. It’d be great if I could have some advice, should I be worried, is this my period, do you think I could be pregnant? Anything that could help me rest easy. I don’t want the possible baby harmed, I just don’t know what to do. Please help? Thank you.
