TTC and frustrated!!! 😡

Lauren
My husband and I have been TTC for 3 months now. I'm a middle school teacher so I can't really afford to be gone at all during the school year. We were trying to time it so I would have our baby during the summer so I wouldn't have to miss any school. 
Well, I am now 6 weeks late on my period and still negative pregnancy tests. This week is supposed to be my fertile week but who knows anymore cause my periods are all out of whack!!! 
I'm just ready to see that big plus sign- this is our last month before I would have to miss work to have the baby. Even now is pushing it because I'll be having it in late July! 
I'm just frustrated.Â
