I am in the exact same boat! I have been getting blood work done to test my cycle and see if I am Oing. I used opks this cycle and low and behold, I got a positive on CD 14 (which is Oing average for 28 CD). THIS NEVER HAPPENS! I couldn't BD that day as I was out of town but BD'd on CDs 15 and 16. My temps have slowly gone up and FF just put a crosshair for me Oing on CD 15. I have to get bloodwork again in a few days to test my progesterone levels. There still is a chance that I could not be Oing...(lord I hope not!). I would think that if I tested negative with the opks the day after and before the positive, then I should be.
I am happy that you are getting the ball rolling to see what needs to be done for your ttc journey. My gyn is wonderful and very optimistic. She told me that if I am not preg this month, that DH needs to get a SA...You'll get there! I feel so much better about ttc after having the support of my gyn guiding me along the way...hope you feel the same way

LOTS of

for you!!!
