thank you for your query.
what you were experiencing is called as breakthrough bleeding
.this is a common side effect of the OCPs.
Breakthrough bleeding (BTB) is usually referring to mid-cycle bleeding in users of combined oral contraceptives
,as attributed to insufficient estrogens. It may also occur with other hormonal
generally it is associated with abdominal pain
and cramps or uneasiness.
delayed periods is also a side effect of OCP usage.
generally breakthrough bleeding resolves on its own.Breakthrough bleeding that does not resolve on its own patients are advised to try different pill formulations, or to switch to a non-hormonal method of birth control.
i think the current pill is not suiting you,hence i advise you to consult your OB/GYN to change your pill.
wishing you good health
