I am 12 DPO, and having pregnancy symptoms. I haad the MIRENA for 2 years this month, and it came out last month. The doctor said I would ovulate around the 5th, took OPK, I was ovulating on the 5th and 6th! Had unprotected sex the 2 days before, during and 2 days after. Having several pregnancy symptoms, can't even ride in a car with someone without getting motion sickness! According to the Dr., my period shouldn't be here for 2 more days. Last night I had bright red blood, only when I wiped. Then this morning, a little darker, but only when I wipe. Could this be implantation bleeding, or did my period come earlier than predicted?
