Period

Hi I haven’t had sex in about 6-7 months I’m extremely paranoid person I basically just need reassurance. I’ve had periods every month since then and I was late a couple days every month which is normal for me. It was a normal period each month. When I did have sex he did not cum in me. And I know that you can’t get pregnant from precum. I’m about 4 days late rn it can’t be from pregnancy right..sorry I’m just really paranoid I just need reassurance...
