Small gestational sac 😟

Grace

So I am supposedly 5 weeks 4-5days and had my first u/s today. Dr said my gestational sac is measuring small. I have pcos and went through 2 rounds of clomid before conceiving. M/c'd at 8 weeks last summer. Going for bloodwork today, Saturday, and Monday. anyone have the same story with a healthy pregnancy? I really need prayers and some reassurance, please!
