Side cramping/ovulation?

Every month I get these sharp side pelvic pains that hurt so bad every month they are on different sides. And my periods are irregular. And recently I jus started doing research to figure out if it could be the egg. And I had sex the first day of it starting to pain could it be possible that I am pregnant? Some symptoms I have been noticed are nausea, increased appetite, and fatigue. According to Flo my period starts In a week also. It’s driving me crazy because the anticipation is killing me I have to know if I am pregnant or not, this will be a long week. have anyone of you experienced pregnancy after sex close to ovulation pain??
