Paranoid!!!

So my boyfriend and i had sex last weekend and were unprotected for like one or two strokes then he put a condom on . This weekend all we used was condoms . But i keep experiencing bloating and lower abdomen pains and my boobs look bigger. Are these symptoms of ovulation (im in my fertile window) , early PMS or is there a chance i’m pregnant? It’s only been like a week or two since we did it unprotected and he’s positive he didn’t cum and so am i because he only got one or two strokes in, but i’m still paranoid . Any ideas ?
