I need some advice! So I've had 2 mc and just found out I am pregnant. Now my last period was on May 10th so that puts me at about 5 weeks. However, after having my first appointment for confirmation... Urine test came out positive but when an ultrasound was performed, the doctor could only see the thickening of the uterus lining.. She is going to start testing my HCG levels every two days to make sure they are doubling. I'm so worried because with my last pregnancy when I had an ultrasound at 5 weeks the doctor was able to see the yolk sac... Could something be wrong??? I'm trying not to panic and stress but it's just so hard and it has me so worried. Any advise?
