Up and then down

Hi ladies,

My AF seems to have disappeared and become really irregular. I am definitely not pregnant unfortunately because I have taken multiple tests

My AF cycle has gone from 28 (regular) days to now 40 plus ( but this can vary) I may add that I began to take Maca to improve my mood- stopped ( only took for 1 months are AF was already irregular)

This is obviously really annoying/stressful when TTC.

I am currently on cycle day 44, been experiencing cramps and all my normal AF symptoms for the last 2/3 weeks but no actual bleeding or even spotting

Anyone got any advice? Experiences of this? Remedies to fix this.
