Painful or irregular periods can be infertility signs. Often times you need medical tests to diagnose infertility. I needed a diagnostic surgery to figure out what was wrong.
At 32 I'd always been perfectly healthy which is why after the 2nd miscarriage (two cycles back to back) I lost it in my dr's office and said if there's a problem I want to know. I was referred on and after testing it was discovered I have a blood clotting issue where my blood is too thick. I was told to take baby aspirin and now have a healthy son! I have always donated blood so to be told I have a blood issue seemed odd - but - a little aspirin helped me carry a healthy pregnancy and have a healthy son!
