So the last time my husband and I had sex was around Nov 19 (and according to this app one of my most fertile days) I was supposed to start Saturday, and have been having some heavy mucas like discharge and bad acid reflux for about a week & I think I smell different down there?? I took a test yesterday and it looked negative but I'm still noticing some weird things. I'm normally very very regular. Like clockwork. Possible it was too early to test? I just want to know one way or the other...
