I had my period on May 16, and I go every 28  days. So I should have my period on June 12th. My husband and I had sex on May 24th and the 26th and June 2nd. The last 2 days I have been having some pains (not really sharp pains) in the stomach for a minute and then it will go away, and then it will start hurting again. I've also had bad headaches the last 5 days. Can you ovulate twice or what?
