Low progesterone ?

ive had multiple miscarriages sadly, my last one was in september 17. i only had 2 cycles in between each miscarriage and became pregnant again. my periods are very regular, good normal flow & i track my ovulaton dates. We been trying to conceive again since november and i know it's still early but cant help but worry if my hormones have messed me up. I've had 4 cycles now since miscarriage and was really hoping i would become pregnant. Could it be i have low progesterone level now due to the miscarriages ?
