Baby dust please! I'm losing hope :(

So my husband and I have been TTC for a year and two months now with no success. I've had a couple of completely regular periods and a couple of not so regular periods. My last one was one of the not so regular ones. it came right around the time it was supposed to but the actual bleeding only lasted one day and then turn to brown spotting which only lasted for an additional 3 days. I really thought that maybe it was implantation bleeding so I took about 3 or 4 test and all BFN. My tender breasts came early this cycle and I've been feeling some cramping but that could just be my cycle starting again. My husband and I are both losing hope. We just need some baby dust and support, it's starting to really bum us out. Thanks to you.
