Need advice/answers

So, I'm on the pill now but as I took it before my period it is not yet effective for a few more days. A couple of days ago I did the pull out method and as soon as my boyfriend pulled out he came. I'm really worried some went in me but I'm originally meant to be due for my period which I have symptoms from and there are symptoms from the pill so how will I know if I'm pregnant?! I haven't had morning sickness but I'm getting paranoid. My boyfriend said he knows it didn't go inside me but I'm just worrying a lot
