Progesterone help

B

Ladies who have needed progesterone supplements... is it too late to start taking it the day you get a positive pregnancy test? I talked to my doctor today and she assured me to just get my progesterone level checked the day I get a positive test and if it’s low she will give me the supplements. The more I read online the more I’m getting worried that I really need to start them the day after i ovulate.

What’s your experience and do I need to push for something different? I am trying to do everything I can to not miscarry again.

Thanks!!!
