My dr asked when LMP was and i told him, and he kept asking if i was 100% certain. Back then my body was like clockwork... 28 days spot on without fail.

We know when DD was concieved for sure....i used to have a program that worked on your cycle and said DTD on this day for a boy/girl, low/medium/high chance of PG, and when id O. The night we DTD my program said 'High chance of conceiving'. One day out from O.....and here is my lil girl today!
