Cramping and low progesterone

Long post, so bare with me.

I had my twins 6.5 years ago with fertility help. They were born at 23 weeks. 1lb 7oz. Spent 114 days in the nicu. Fast forward April 19th much to my surprise I had a positive pregnancy test... and 30 more after that. I have PCOS and endometriosis. I was told I could never get pregnant naturally. Immediately with my history, I call my OB because My last period was February. Not uncommon however for me to not have a period but there’s no telling how far I really was. She checked my hCG 1 a week for two weeks. Levels looked good. Booked appointment for tomorrow may 18th. I went to those fun outside places that do ultrasounds they had me at EDD of Dec 29. (6 w1d) they did both vaginally and abdominal us. Abdominal was fuzzy but could still still baby and flicker of heart beat. Well on Thursday I had pressure and it lasted all day. It was a familiar feeling- like when I went into preterm. I called my OB and she called in hCG and progesterone test. hCG looked fine but Progesterone was like (8.4). She started me on oral progesterone pills. Yesterday I went to an outside facility again to get a us. Not a medical facility but a local nonprofit place that helps expecting moms make informed decisions and education. Their machine was over 20 years old. They did abdominal. My bladder was not full. Saw a sack but no baby. They told me to be optimistic but it’s hard. I’m still cramping consistently. It’s not unbearable but it’s annoying! No bleeding still. I guess my question is if you around 7 weeks 5 days have you had your progesterone checked? If so where are you at? If not prayers and good vibes would be much appreciated. This is a cruel joke to go through all this and ends up miscarrying. There is more to the back story but let’s just say this baby is a freaking miracle! Thank you! baby dust to everyone!
