Now 11 days late

It's very frustrating to be actively trying to conceive and to be this late with so many negative pregnancy tests. When I arrived home today I had a nickel size mucus clot that was brownish as well as cramps for most of the day. Assuming I will begin my period tonight or tomorrow. :( which when I go back to last months fertile days and ovulation day changes if I start now then ALL the days I had sex (which was ALOT) were all the wrong days!!! I know it's really in His hands. Just hope He intends for me to have another baby. I want Sam for have a friend and someone to grow up with and make memories with. When we get old and die I want her to have family. :) that's all.
