Hi - I'm new to the board and new to all things infertility.
Been trying to conceive for 9 months, am 38. Tried my first OPK last month, and I got no LH surge and started to freak out. Roaming around these boards, I understand this is not entirely uncommon, but I still don't understand why. I have regular menstrual cycles, lasting 25-28 days, most months right at 28. I have started the process of getting a referral to a fertility specialist, and my PCP just sent me a lab slip with no directions on it.

He ordered the usual - Estradiol, FSH, LH, and Progesterone. But then I assumed that there must be specific dates to take these tests on. I know that FSH is Day 3 of my period, but can the rest of the labwork be done that day as well?
So I am slightly clueless, in the early days of wondering about infertility, with unhelpful doctors. So any advice on this whole no LH surge thing, why that would happen when I have regular periods, and advice on lab testing, would be greatly appreciated!
