Thank you for developing this product. At first I though it was alot of money, however, after getting an estimate for $20,000 for IVF, it seemed like a small price to pay for the OVwatch. I was scheduled to go for IVF in January 2008. At 40 yrs old my time was running out. We had all of the preliminary IVF testing done, genetic testing, endo biopsy, Hysto test, etc. They couldn’t find anything wrong with me. My husband and I have been trying to get pregnant for 2 years. Turns out, I ovulate later in my cylce than Dr’s said I did. We were all sexed out by the time by ovulation was occuruing. I got pregnant the 2nd month with the watch! BUY THIS WATCH!!! IT IS WORTH EVERY CENT!
