Low progesterone

Lindsey
Any ladies have a miscarriage with low progesterone and it only be a one time thing? I got my blood work back and my hcg was already a 4 when tested and they said my progesterone was really low so next time I get a positive test I have to go in right away for blood work. I'm doing a ton of research on low progesterone and what I can do, I'm just wondering if it's happened to anyone and it was just a one time thing or if I really should be concerned that this could be a problem. Thanks!!
