Is it premenstrual syndrome or pregnancy? I had unprotected sex during ovulation, in the last two weeks my breasts hurt a lot and even I have increased the size. During the last week I also had much back pain.

I can not tell if you're pregnant, but it is a possibility. The implantation of the embryo in the uterus may cause bleeding. These losses are usually brown, pink or red mixed with white. Vaginal secretions become more consistent and thick and increase. The classic symptoms of pregnancy did not show up until it is produced or after the first failure. These symptoms include sensitivity and inflamción breasts, nausea or vomiting, lack of menses, increased need to go to the bathroom, headaches, insomnia, fatigue, mood swings, antonjos, gas, loss of waist. The best way to know is by testing. Buy the test the first day of the absence.
