I had unprotected sex on the day of ovulation which

Patient: I had unprotected sex on the day of ovulation which was yesterday and again before ovulation on the 7th of this month and I am worried I may be pregnant or whether its just pms I should have my period in around 2 weeks time but I have been having sore breasts and feeling gassy and have had an itchy labia, the sore breasts stated on the 8th so that day after I had sex and it was really bad. I am also stressing about it and I wondered if stress can cause these symptoms and my body is being fooled that I’m pregnant can this happen?
