So confused!!

MeLissa • Army wife 12/13/14. Not trying, not preventing. Waiting until after college to continue trying for our first!! Just living life to the fullest! 😍👗🌇
So.. I had my period the 23-28th... I took two ovulation tests these past two days (not with FMU) because my husband will be in the field for a week and didn't want to take any chances (and it eased his mind a little bit) well the test say there won't be any line if it's negative but the two tests I took showed two lines but the test line isn't as dark as the control line and it's only getting lighter. Is there some way I already ovulated? Or is it possible that the tests are just negative and I'm reading too much into it?
