Preseed?? Any feed back?

Just courious if anyone has had any success or has tried or is trying pressed? I just bought my first box today. But not sure when I will be ovulating yet because of a cyst they found back in October. It has me all screwed up. We've been trying to conceive for 2 years in January. And we are both in our early to mid 20s. And so ready for baby number one.. Also what was your experience with it? Thank you everyone!!
