Asked for female, 23 years old from Hyderabad
Since how many months is she on OCP.
Breakthrough vaginal bleeding is common between expected periods. This usually resolves within 3 months of starting to take the pill.
During spotting, the pill is still effective, as long as it has been taken correctly and no doses are missed. This bleeding may happen because the uterus is adjusting to having a thinner endometrial lining or because the body is adjusting to having different levels of hormones.
If she is using OCP since March, then she should contact her gynecologist for advice.
