Does it’s normal ??

Any one have 5cm follicles like me?

I have used Follistim to help grow follicles and have 2 matures egg! I had trigger shot 1 day before

IUI on 8/14 !

After TWW i got negative test and my period show on 8/29 so i thought i start new cycle!

But today ( CD3 ) i came to ultrasound and blood test and see my egg still hanging there and it’s giant-5cm! I never see that before 😱😱

The dr. said because i had 2 matures egg but just 1 response to trigger shot and released another still keep growing! It’s make me so scared! Does is it normal ?? Anyone like this before?
