It's been almost 2 weeks since miscarrying and I finally got a negative pregnancy test. I took an ovulation test and got an VERY faint 2nd line. I've never used them before. Does the line get darker each time you test until it's really dark as a positive ovulation?  We are going to start trying right away, so will be having sex every other day or so anyway, but I will be taking ovulation tests to help.
