Query: Nearing the end of first trimester...

My husband and I decided to officially start trying to conceive in April of this year, and after reading all of the positive reviews, I bought this monitor. Coming off of the pill had made my cycles pretty irregular and I really didn't have any idea about when ovulation was happening. During the first month, the monitor was just getting to know my cycle, and I think our timing was a little bit off, so we didn't conceive. However, timing worked perfectly during the second month and now I am in my 12th week of pregnancy. The time window in the morning was never a problem, the monitor is easy to read, and though it can seem like an expensive investment, it seems like a such a small price to pay in exchange for quality, accuracy and the relief of knowing exactly what's happening with your cycle.
