How late was your bfp?

Dh and I have been trying for almost three years and it’s been so emotional, I was giving up.

We didn’t get to try but a few times that I forgot to log because I was trying not to stress, I take metformin regularly and this was our first month on Letrozole. I figured we were out since we didn’t get to BD much, but then I realized I was LATE LATE. I’ve never had a cycle this late. Cd 44 today.

Took a dollar store cheapie Wednesday the 28th, I tossed it almost as soon as I saw it was blank.

Thursday, around bedtime my back had that sharp pain like my af should come on and thought I was out but that was it. Here I am Saturday and still no Af.

Should I test again?

Should I contact my doctor?

Is it possible I’m late because of the medicine?
