Ok so it says that my period is due on the 18, I don't know if this is normal but I get my period every month on the 14 with out a doubt. What's up with this? Any help out there please to help me correct this? I am TTC but no luck so far. I took an ovulation test todat and I think I'm ovulating because there was two lines the same color, so I had sex today, my CM is egg white. I'm confused. Really confused...
