When is it going to happen???

Samantha • TTC MONTH 14
Just took my 2nd pregnancy test this fortnight after being 2 weeks late and once again got a BFN! When will it happen? How can it be that I am struggling to do what Mother Nature wanted females to do? TTC Month 11 and I'm not sure I can take much more of tempature tests, ovulation tests or handstands after sex. I think I am at my lowest point and I just want to give up. Who knew that TTC would be so hard when most of my friends just had look at their other halfs. I feel like a failure - sorry for such a depressing post I just feel so low right now.
