Follicles and Betas before and after IUI

Hi everyone!

I had my 2nd IUI on 4/26 after a miscarriage after my first IUI in February. This was successful as well. I had two follicles- One on each side when I had my ultrasound. I know with two follicles there is a chance of twins, and we will adapt to that if it ends up being so. I had my first Beta last Friday- it was 117 at 14dpiui. My second Beta was today- it was up over 500 (72 hours after the first). Does this sound normal? I’ve never had a desire to have twins so I’m nervous. I know no one can tell me for sure what is going on in my Uterus but I am looking to hear your experiences.

Thanks!!

Jen
