thank you for asking for a help.
the treatment you are following for your irregular delayed cycles is very wrong.
your problem can be called as secondary infertility
you need to look for an obstetrician as soon as possible.
you may need hormonal
study as well as ultrasound
guided ovulation study.
kindly don't self medicate your self each time your cycles are delayed , as this has its own side effects and may decrease your chance of further conception.
do consult a good doctor and undertake all the required investigations, and see an infertility clinic if required.
