Im not sure if i have low progesterone levels or not, im getting bloods done on day 21/ 1 wk after i ovulate this cycle. Iv had 2 early miscarriages this yr (1 this wk) so i kind of feel its time to rule it out....however my doctor is fairly useless and i feel there's ladies on here who know a lot more about this! Just wondering if its by prescription/over the counter? If you actually dont have confirmed low levels could it mess up cycle/ harm a pregnancy? Ive heard of creams and suppositories- which are better? Any info would b great.
