Thanks for the query.
After stopping pills it will take some time for regularization of periods.
As after stopping pills the hormonal
levels in the body will alter that may be responsible for delayed periods and scanty flow.
In case of irregular periods
it is difficult to predict the time of ovulation and chances of conception.
So you once go for blood test
which will rule out the possibility.
If the test comes negative you watch the menstrual pattern in the next month, if any abnormality found at that time also go for an evaluation.
