I am really tired but don't want to miss our chance this month, so can anyone help me out? I have been using the Clearblue ovulation sticks for the past 4 days. On Sat there was a faint blue line and yesterday it was very dark (darker than the other line). Today it is faint again. We have bd the last 3 nights in a row, and I am wondering if I can have a rest tonight as the main peak has passed or should have one more go? Does the strongest line mean that day is the best bet, or the following day?
