Pregnancy ? pms?

I had unprotected sex about 3-4 days before I ovulated (I track ovulation with strips) he didn’t finish inside but I got concerned of the fact I could get pregnant with precum . My period is supposed to come on the 19th these past days I’ve been having light cramps sore breasts and horribleeeee acne, and super emotional I usually get symptoms like this before my period but does pregnancy cause this symptoms 2 weeks after having sex?
