I need help! Am I pregnant!?

I never get back aches from my cycles and i haven’t done anything at all like lifting heavy objects or sports or working out my period is due in 9days I also have been having odd cramps in lower stomach and yesterday had dull pain there but today I didn’t notice much I’ve been very tired feeling all day slight headache and dizziness and I my nipples are slightly sensitive but my boobs are not I had unprotected sex twice a week ago when I was ovulating and had the highest chance a day apart from each other but used the pull out method if I was pregnant isn’t it to early for symptoms to be showing? Also the first time he pulled out and came on the top of my vagina then wiped it down onto my vaginal opening with a towel is it possible it got inside me or the towel absorbed it? I’m sure I’m just a little paranoid
