Hello I'm 23 and Me and my husband wanting to start TTC. Couple days ago I just wanted to get checked and get my progesterone levels checked because my sister had a hard time TTC because of progesterone being low. I received the results and it's .5. I tested on CD 21. Since it's the weekend they haven't responded on the results. But told my sister she said it's kinda low. I'm alittle worried. Any advice on how to naturally increase it.
