HCG and Progesterone rise and level during 6th week

aloha7

HCG: 5w5d 13962

6w5d 46736

Progesterone:

4w5d 83.9 nmol/L (26.38 ng/mL)

6w5d 75.7nmol/L (23.8 ng/mL)

I am concerned about the slow rise of my hcg between 5w5d and 6w5d..? It is not doubling every 2 days but every 4days! Anyone knows about this? Does hcg rise slower during the 6th week?

My other concern is my progesterone. It seems too low at this stage. I am taking natural progesterone supplement (vitex/chasteberry tincture) and even with that it is still pretty low. I hope it does not mean ot is just a bad pregnancy?😭😭 like a missed miscarriage? I am gonna request a prescription progesterone and start tmw but i hope i am not too late? this is so hard

My first ultrasound is this Friday, at what i should be 7w5d. I am beyond terrified to go. I have had 2 missed miscarriages and 1 sponataneous miscarriage in the past. (also had a live birth after)
