Just need a bit of ov test advice please. Am using the cheapie Amazon tests, and started a new batch yesterday. I had a bit of a shadow line on Tue, but think it wasn't for real as it came out some time later on. Yesterday and today (days 16 and 17) I've had fairly strong lines to say the hormone or whatever is up. So this means I am ovulating about day 17/18, is that right? Is that likely? My cycle's fairly consistently 27-29 days and until I started the testing we'd focused (ahem) on days 7-14 really, as I thought it was all about day 14.
