I had my HCG taken on Monday it was 4664 and today 7106. My progesterone is at 19. It was at 21. They are starting me on progesterone. The doctor said my hcg only increased by 53% and they like to see 60% increase. I am worried this will be another miscarriage. I am 5 weeks and I have had light spotting on and off. I am afraid this will be another miscarriage. Anyone else have a 53% hcg increase and go on to have a healthy pregnancy?
