Teacherlynn- My friend found out she had a blocked tube so it didn't end up working with her but she is getting IVF Next month!
I went to the doctor in January because my cycles have been all over the place (30, 153, 70, 40 days) and she kind of told me to "just keep trying" and taking opks daily.. she said if I don't get pregnant on my own by May, she will see me again and probably prescribe something. But here we are mid march and I have ovulated once since December.
Wrap- Your surge could have been super short- I think I read it can be as short as 4 hours. So if you only tested once that day, it could have come and gone. That's why it is good to also temp, so you can confirm that you did O because you would have a spike.
