Feeling very low

I think I’m just done with all this. I’m now five days late and another negative test with a pink dye and fmu.

I know people are going to say to try again in a few days, it can take time for the levels to be high enough etc etc. But everyone on here gets their positives anywhere from 7dpo and mine aren’t even a shadow of a second line! I’m already very low chance of getting pregnant because my partner can’t finish most of the time, we hardly ever manage to time it right, and now my body is being stupid and I’m missing a period!!

I feel so miserable and defeated. I’m not sure who I’m more mad at either, me or my partner, we’re both the problem really. The one thing my body should be able to do and I’m failing.
