Pregnant ?

I had sex 2 weeks ago and my period is due in a week n half. we used a condom and he pulled out before he came. i was a couple days away from ovulation, but when we had sex i was still on my period but after we had sex a bit more brown blood came out. if something could’ve gotten in me from the outside of the condom could it have gotten washed out? im really nervous. ive been dizzy for 5 days now anytime I get up, and today I felt like throwing up but couldn’t. i also broke out on my face. could these just be pms? im freaking out 😣
