OPK question/need advice
So this is our 4th cycle ttc and our first using OPKs. Anyways on the 6th I took my first test and ever since then they have all been positive. The test lines have all been way darker than the control line. They aren't fading at all. Except for one in which they were both the same. I haven't temped because I heard that it isn't very reliable. But maybe I should start. People have told me maybe I am just having problems ovulating but I had fertile cm around the first and second opk and now it isnt. So I really think I already ovulated. Anybody know why this might be?
