I am due for my period on May 2nd but I have been continuing testing with OPK just in case I ovulate late. Anyways I was getting like super faint nothing lines then all of a sudden I am getting progressively darker lines? I don't think I would ovulate this late in my cycle and I have done a lot of reading on the internet about people getting positive OPK late in their cycle and finding out they were pregnant. Obviously these are not positive but I was wondering if anyone had a similar experience and what the outcome was?
