Hi Dr Sher,
I got covid during my ivf cycle last month, so had to cancel D9 after taking corifollitropan alfa D3.

I got my period early on D19 (usually have 28 day cycle) and my D2 E2 is 138 pg/ml. FSH (6) and progesterone (0.9).
My D2 E2 has always previously been <60.

Is the likely cause of high D2 E2 a functional cyst? I’m repeating bloods to see if E2 levels come down. Should I be getting an US?

Thanks!
