TTC and frustrated 😡

Lauren
My husband and I have been TTC for 3 months now. I'm a middle school teacher so I really can't afford (monetarily and otherwise) to be gone at all during the school year. We were trying to conceive so I would give birth sometime during the summer. Well, that time has come and gone. 
I'm now 6 weeks late and 6 negative pregnancy tests. This week was supposed to be my ovulation week but last night I took an ovulation test and it was negative as well. 
I'm getting beyond frustrated and starting to lose hope.Â
