My Periods are so Irregular & I Have Been Using This App For 2 Years Now && For some reason . I have yet to receive a BFP ?? Like what am I doing wrong . I log everything the way I'm suppose to every day . I have sex every other day & I Us the ovulation kits and every thing & for some reason I still haven't got pregnant. I'm starting to believe I just can't have kids .. I even used clomid for a month & I take prenatal vitamins every morning..
