I had my IUD removed Aug 22, 2014 and started my period Aug 24, 2014 lasted until Aug 29, 2014 and then started again from Sept 5-8 .. How will I know when to ovulate since I had two periods !? I had unprotected sex on Sept 12 and I am now having "twinging" on my left side and some overall cramps! Anyone know if this can be pregnancy or preparing for my next cycle ? Help help help !
