My HCG levels at 4w3d was 72 and 4w5 was 142. Just got them drawn again today at 5w5d. Nervously waiting for the number!!! They are watching me closely due to a miscarrage in November. Today marks the day that one of the twins died (there best guess). Even though we didn't find out until 9w. I'm a bit of a nervous reck right now! The other twin passed at 6w3d. We will be getting an ultrasound around 6w3d. Keeping my fingers crossed and trying not to think about it too much.......
