Bleeding and low progesterone to late??

So long story short I have needed progesterone In all 4 of my pregnancies. My body just dosnt produce enough to sustain a pregnancy. This one, again my hcg was “amazing but progesterone at a 6” and wouldn’t give me supplements until a sono even though they know my history. Not even an hour later I start lightly

Spotting and went to ER where they confirmed

The pregnancy was in my uterus still with a yolk sac still holding on but I needed to wait for my dr to prescribe supplements. Well I go home and go to bed and wait for the miscarriage as my cramps were picking up and the spotting got a smidge darker brown but no clots yet or heavy bleeding.

My friend had one tube left so I started it and the cramps stopped and the dr called saying she’ll start the supplements

For me

Since there was a pregnancy in the uterus.

My question is bc the spotting got a little heavier and I’m sure In 36 hour waiting time

My low level of a 6 dropped a lot more,

Does anyone have any experience with low progesterone and bleeding and still going on to save it with supplements? Any help to ease my mind until Monday would help 🙃
