ANYBODY ELSE UNSURE!!!!

This is only my second cycle trying. The first cycle I felt I did everything right. I even had what I thought were pregnancy symptoms but that pregnancy test at 12DPO proved otherwise. I want to keep trying some days but then I end up getting so discouraged during others. I want to be able to go through a cycle and get that BFP at the end. I'm only 28 so this should be easy right??? Nope, this is the hardest thing I've ever had to work for. But they say "nothing worth having comes easy, and nothing easy is worth having. I'm trying to keep the faith but after that abortion 8 yrs ago and now wanting a baby so badly its so hard. Maybe I'm over thinking things but I still remain UNSURE.
