Estradiol levels

Si

Just got bloods drawn for day 4 of stims. Estradiol came back at 386pg/ml. At the same stage of stims for my previous retrieval it was at 198pg/ml.

Any advice/experience if this is an indicator of more follicles or larger follicles earlier? I guess it could be either/both.

Now to wait for my day 5 ultrasound tomorrow...

Update: I think I did have a couple more follicles that last time at this stage, but the main culprit was that on follicle was at 17mm already, while the rest were between 7 and 9 🙄
