I have a slight pinch or pulling feeling in my lower left abdominal area. I have had unprotected sex on the last day of my period, and up to 9 days after my period. My Husband and I are trying to become pregnant. Also with my other child I experienced mild irregular bowel movements varying from every 3 days, which I am experiencing now. My last period began on the 9th and ended on the 14th of April.
