Cycle day 50..bfn today!

I'm at such a loss at this point. Last af was 3-21 and I keep getting bfns. I have symptoms on and off simulation to af showing and then nothing..

I have a doctor's appointment for the 16th, I purposely made it that late because I was hoping it would just show either way by then but now I'm unsure! I was just out of town as well to get my mind off all the ttc thoughts and I did feel better when I was gone.

Anyone else have any experience with this?
