At 5w 5d I went for my first ultrasound and was told the gestational sac was only .48cm and measured 4w 2d. Blood drawn that day with progesterone level a 10.

I know there isn't a mistake in dates because I was using cb fertility monitor and it measured my fertility levels every day for 20 days of my cycle. I also meticulous kept track of days we BD'd and whether it was during a fertile period (checked my ovulation tests and cbfm).

Blood drawn two days later (6wks) with progesterone levels still a 10. Hcg levels at 5,000 - "basically the same" as two days prior.

Slight pelvic cramping on right side (where cramping was around implantation and early pregnancy). Ultrasound shows gestational sac at my 5w 5d dr visit.

I just want to know what this is. No sugar coating. Dr said could be a slow grower but my progesterone is low and Hcg levels should be increasing. They just stayed the same.

Please share your experiences so I know what to expect!!
