There is a thread around here somewhere for ladies using MaybeBaby. I ended up giving mine away to another lady on this site. I much prefer buying OPK's to maybebaby, because they are far more reliable, and I can never pass up a chance to POAS . I bought the cheaper version, on ebay for 30 or 35. My opk's are 20 for $10 or $15 i think. The maybebaby was a bit too hocus pocus for me. Good luck!
