What are the best vitamins to take if i have irregular periods and i'm trying to get pregnant?

Might be hormonal: If you are having difficulty with getting pregnant, there are many possible causes but one important one that is easily remedied is hormone balance. Ask for a luteal phase lab draw (done on day 18-21 of cycle) and get an estradiol, progesterone, dhea-s and pregnenolone test. If any of these hormones are low, pregnancy could be more difficult. Re vitamins, a good multivitamin with minerals.
