me and my boyfriend had unprotected sex for a while. I was suppose to get my period on the 19th but ididn’t get it . So then two days ago at night me and my boyfriend has unprotected sex again and he wanted me to take the plan b pill bc he felt as if he came in me alittle. And now after taking the pill I’ve been spotting. Can this be from the pill or  can i be pregnant since i had already missed my period? Im confused .
