I only ask because my last cycle lasted 100 days and my OBGYN gave me Provera to help me start. Well it worked but now that I am on a new cycle glow shows this as the first day of my fertile window, NO positive OPK yet and I'm starting to get scared I won't have one. What day do y'all usually start getting darker lines on your OPK? What day do you usually ovulate. I was so psyched to get started trying again since I finally had my period but now I have a feeling this is going to be the next obstacle. We have already been trying for 7 months which I understand isn't a lot to some but it feels like forever to me considering our daughter who is now 5 was not planned.
