An Update

So just to REALLY mess with my head, I sent the clinic a message yesterday asking about the numbers, since I hadn't heard. Got this about Friday:

Hi Aly, Yesterday E2 was 686 and P4 was 3.6. Sorry you didn't get a message. (On Wednesday, E2 was 495 and P4 was 4.4.) 

So it's dropped again. Surely that means it must have been residual progesterone levels from the chemical pregnancy last month? And what does it all mean? I guess we'll find out on Monday.
