Just a quick question:
I know the CD21 is usually what they use to confirm ovulation. I am CD18 and am about 97% sure I ovulated on CD14, as per my usual.
I had a BT today to confirm I've ovulated, but my question is, will it be able to tell, given it's on CD18 and not 21?
I assume it's just looking for low estrogen and higher progesterone?
