In March I had my period on the 23rd, and in April I got it the 20th, it ended the 24th-25th. So I had it early. I have very short cycles. Anyway, my boyfriend came in me the 29th, but it was near midnight so the 30th. I was just wondering what are the chances that I will become pregnant? I don't want to get my hopes up but I used an ovulation calculator and it said that was the best time to do it. Thank you in advice, I'm 20 btw. And do want to be pregnant.
