Frustrated

My IUD was removed April 2015, and we have been TTC. Its so hard to track my period, the first time we were TTC I wasn't on any kind of birth control before hand so I knew my cycle pretty well and I got pregnant so fast. This time around it feels so much harder to do.AF is due Saturday and all I want is a BFP! We lost out first baby at 5 months old and I have no patience!!!  😫
