Im So Frustrated I Dont Know What To Do Anymore

Me and the hubby have been TTC#1 for over a year now. My hopes have slowly began to decrease. In the beginning, we really didnt know about tracking and the ovulation dates and once we hit the 6 month mark the doctor told me work on that and in 6 months come back. Well I have and it seems that every month I track it and we TTC around the time of my "ovulation" notihing happens. We thought we were pregnant in June. I was actually 6 days late and all 3 tests were BFN. And it bothers me everyday I come to work, because I see all these women with big bellys and its like all the odds are working against us. We have an appointment to talk over fertility on the 6th of August but its just so frustrating. Money is always tight and buying OPK's and BBT thermo's AHHH We actually thought about just having sex everyday this coming month. I mean would it hurt? I actually read a study that men who have sex everyday increase the sperm productivity. So maybe? I will be getting out of the Army soon and would love to get prego around that time. we want this so bad and it seems like nothing will let us
