I just got my second beta HCG today and it only went up by 2. Monday it was 53 and today was 55. It is supposed to double in 48 hours. My OB said it could be a lab error because it is so rare to see a good progesterone level like I had and not a good HCG rise. I am getting the beta and progesterone drawn again on Monday so really all I can do is wait. I don't understand why this is happening to me again. I left work early because I work in a NICU and I couldn't take it anymore. It wasn't the babies' fault but I couldn't take care of them anymore today. I hope Mondays test is better but I am preparing for another loss. Thank you girls for all your support.
