This month was my first month using OPKs. The test line was never darker than the control line. Could I still have ovulated? Right around when I should have there were two lines (test line ALMOST as dark as control line). Before and after there was only one line. My other question is does the test line need to be a solid as the control line? When I would test I couldn't really tell if the test line was as dark as the control because it wasn't quite as solid.
