What's going on??

Lisa
So my hubby and I haven't been actively TTC as far as ovulation kits, or treatments go, but we haven't been using birth control since Dec 2012. I had an early miscarriage in May 2013 and since then no signs of pregnancy. Now I'm on day 43 of my cycle (average is 29 days with shortest being 25 and longest 41) and am still getting BFN on my tests. I know somethings going on as I feel things in my body. I just wanna know if I'm pregnant or if there's something else going on...
