Te cause of your irregular bleeding should be determined first in order to get the desired results. Blindly starting deviry
is going to be of no use.
The cause can be hormonal
disturbance, PCOD,thyroid disorder
and very benign as excessive weight.
If you are sexually active than in the event of prolonged spotting pregnancy
has to be ruled out.
Do consult a gynae and get fully investigated before resorting to any form of treatment
