This might help someone if their not taking any special vitamins because they don't know which ones to take.

Last cycle I started B Complex and it delayed ovulation and lengthened my luteal phase. Which mine is 11 days, anything 10 & under will make it hard to conceive. This cycle, I started a new prenatal which has DHA(fish oil) in it. You should be taking a prenatal that has DHA in it. Helps promote fetal brain growth and defects. I am still taking B Complex, along with Calcium with Vitamin D3, Magnesium, Probotics with Cranberry(this is for me - I am prone to UTIs, you don't need this unless your PH is too acidic like mine). I take Calcium, Magnesium, and Cranberry to help conceive a girl. But your body needs Calcium and Vitamin D. I also started evening primrose oil - helps produce the right CM.
