Pregnancy or am I just paranoid
So I had sex about two weeks ago and the day after I got head about a day later I got a yeast infection I read online it’s could’ve been from the head I got but it also said I could be pregnant. I’ve been bloated constipated, gassy, extra tired, mild cramps and just now my lower back started hurting and I’ve got tender breasts. My periods also five days away but I am really scared I won’t get it and I might be pregnant. I read you can get pregnancy symptoms within a week can someone help and tell me what might be going on???
