Hi, Welcome to Health care magic forum.
You have irregularly irregular periods
, means can't be predicted.It usually happen due to the anemia
, or infection, or harmonal imbalance like poly cystic ovarian syndrome.
In such case it is difficult to caliculate the ovulation time. So i advise you to consult a gynecologist for diagnosis and treatment. There will special vaginal thermometers to see the temperature . On ovulation day there will a 1degree rise in vaginal temperature.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to have a good health .
Wishing for a quick and complete recovery. Thank you.
