HCG and Anxiety

I found out that I was pregnant on 1/9. It would have been the first day of my period. My HCG was 232.

On 1/11, it more than doubled to 584.

Because I was on fertility medicine for IUI (femara and ovidrel), I’m being closely monitored, so I have to return for a third blood test on Sunday.

Anyone else have this experience and feel anxious about it? When did your REs test you? I’m having a hard time focusing on the joy of being pregnant because it doesn’t feel real and I’m terrified of what might be.

Thanks!
