Some hope for short luteal phase

Today at 9 DPO I got my first ever faint positive. Before this I had a really short luteal and phase for 4 cycles since coming of the pill. Things I did differently: -seed cycling -quitting caffeine and all alcohol - vitamins d, iron, folic acid and B and pregnacare vitamin -yoga videos for fertility Was taking agnus castus and CoQ10 for around 4 weeks but stopped as it seemed to be delaying my ovulation.
