Hi, my cycles have been shorter too. I realised i was ovulating same times but LP shortened and that probably preventing getting PG.ANyways i Have realised stopping supplements no the solution as i have done one try stopping them and got AF. we need to take EPO from CD1 and stop at O and then dont take until AF arrives next time.ALso take fish oil of same strength with EPO to make it effective. The personalised plan gave me too many supplements but this month i am going to try with only taking EPO fish oil and normal muti vitamin lets see then what happenes. I dont exercise and havent followed much of diet but will see how i go this month. Good luck everyone i am still waiting my AF to finish.
