Has anyone ovulated before their frozen cycle while on meds?

I’m on estrace this is my second transfer and my LH surged today so I have to follow up with more bloodwork. Nurse said that if I ovulate I can go into a natural cycle instead.

I’m scared and confused- I did the ERA test and I’m supposed to transfer in day 6 of progesterone now I’m scared that means nothing and I’m on my last embryo!

Anyone been through this?? Should I wait and hope for next month?

I have not ovulated yet I may just have a high LH but I’m just nervous!
