I am pretty sure I am Oing that soon too.
With my 4w loss and my 6w loss, I seem to be Oing right on time CD15-16.
I am CD 15 (I think...without checking my chart) and I have had EWCM, my temps reflect O, I feel the lymph node bump on my right leg, and I got a positive OPK today. I was also really tired yesterday which seems to be a sign of ovulation for me. I get extremely tired for two days around O.
My temp went way up today, but I think it is from lack of sleep. We got a puppy last night and he kept me up all night

So I am pretty sure I will O today or tomorrow.
Good luck to you both and lots of
looks like we will all be in the 2ww together!
