HCG Level

Tiffany

So. My HCG level at 4w3d was 39. It went to 222 at 5w. Now the OB wants a new blood test because its low before booking my first appointment. I didnt ovulate tille CD 19 which is probably why its lower than someone who ovulated at CD 12-14. Should I be worried? Have you heard of an OB wanting to do contsant blood work before booking first appointment?
