Test progression low progesterone

Last night

Tonight

I am having issues this pregnancy (well I have an issue of reoccurring miscarriages this will be my 3rd. I had my first beta this morning it was 19, progesterone was 7.5. I came home and actually started wiping brown blood so I assumed I was miscarrying till I peed on the stick tonight . The line is noticeably darker (even compared to this morning) . So I most likely haven’t started the miscarrying process so why is my progesterone low? I am getting so frustrated and emotional that I am prob going to lose my baby since the progesterone isn’t working 200 my twice a day .

They can’t explain why it’s dropping , I kind of asked for this to be checked the whole time and they said it wasn’t need as long as I on progesterone .

I guess I feel that if I was listened too, had my progesterone checked at 21 days since I had concerns of not feeling the full effects of progesterone tables. Maybe I would still be losing this baby but maybe not. I will never know.
