Implantation bleed?!

Hayley

Currently day 50 of cycle where previous 3 cycles have been 31. Done lots of tests all BFN 😔. Had symptoms of cramping, moodiness and hot flushes at times along with some spots and food cravings!

Today I went to the toilet and wiped and found a very light pinky brown discharge type bleed. This was 4 hours ago absolutely nothing since.

Is this my period or implantation bleed? I’m so stressed.
