I am afraid I can't get pregnant. My period for the month of may started April 30. I had an hsg on may 9 and both tubes are clear. Following the hsg I had sex on may 9. I spotted on may11. Following that I had sex on may 13, 15,16. Then again a few times before the week of my period and then one time the week it was due. My period came on may29th and lasted until June 3. it lasted longer than usual. What is going on? And I am having frequent headaches. Why was my period so long? Help me plzzzzzzzzzzzzzzzzzzzzzzzz
