I had sex on 8/2. expected ovulation was 8/9, expected period is 8/23 in usual 32 day cycle. breasts sore for over a week. chances of pregnancy??

Count on it: Anytime a healthy 21 year old young woman has unprotected sex with a male she should expect that pregnancy is a real probability. The human reproductive system is designed to maximize that possibility ANY time during your cycle. Those sperm will swim around for days waiting to fertilize a newly hatched egg. I'm not a bookmaker but I would hardly be gambling if I bet on a baby in 9 months.
