Well me and my fiancé have been Trying to conceive for about 2 years, this month we timed our sex perfectly, my ovulation was the 15th of Augs, but we had sex on the every 2nd day up to the 12 and then again the 14th which is the day I had light pink spotting for a couple hours then it stopped could I be pregnant or have implantation bleeding before due ovulation date unless I counted my days wrong.
