The first day of my last period was March 1. I had unprotected sex on March 1, 2, 4, 7, 8, 9, 12, and 15. My boyfriend came in me on March 4, 7, 8, 9, and 12. My average cycle is 25 days so I think I ovulated on day 10 but I'm not sure. My next period is supposed to start on March 26, but I can't wait until then to take a test! My breasts have been sore since March 15 and I don't usually get PMS until 5 days before my period. What are my chances of being pregnant?
