I'm on cd19 of my third clomid cycle. I have been opking since cd10. They started off super light and the line has gotten slightly darker. Today it is soooo close to being a positive. This is my first time using opks during a clomid cycle. I'm afraid to get my hopes up because my doctor has cancelled my bloodwork because of a very long af. They didn't seem to think I would ovulate. I wish it was time to test again. My heart is going to break if the line doesn't get darker. Anyone have experience with first response opks? During a clomid cycle? Did yours get darker over time? Any advice or stories? I'm also a little sick. I'm afraid it may mess up my slim chance of ovulation.
