Hello, I just found out I was pregnant last Friday. The Beta was 3,123. My doctor had me retake the blood test on Monday to make sure the levels were doubling at least every 48 hours. The blood test on Monday had a Beta of 4,250. They called with the results today and had me come in to do an ultrasound. The ultrasound showed an empty sac. They had down that I was 5 weeks 3 days pregnant. They said the empty sac could just be because I am too early for an ultrasound. My last period was April 19th and I have irregularly long periods. I think my conception date is May 18th. So 5 weeks matches my date of conception. My blood work this morning had a beta of 5,997 and I have another ultrasound on Wednesday. My doctor is not sure if it is a viable pregnancy or not, but she doesn't sound optimistic. She said not to worry about it and we will look at it again next week. I can't help it, but I am still worried. I took Provera and Clomid at the very beginning of this pregnancy. I was misinformed on how to take the Clomid and my blood test before taking the medication said negative because it was too early for HCGs to show. So right now I am really worried and nervous. Has anyone had experience with any of this? Low rising betas? Empty sac at 5 weeks? Provera/Clomid very early in pregnancy? Thanks so much!
