Ovulation predictor kits and basal body temperature. Oh and to take a BUNCH of vitamins everyday. My new ob always comments on the fact that I make boys only and blah blah, and tells me that I need to eat more bananas and pineapple when trying to conceive and not to have sex on ovulation day but 3 or 2 days before it, so I can conceive a girl. I remember I had sex on O day only, sometimes the previous days and after it, but always on O day. I don’t mind having another boy for my 3rd and last time, actually I love the idea of being a boy mom. But I wanna try those tips he gave me, out of curiosity.
