Hi, thank you for question.

From you question above, i understand that you are having light bleeding after taking the oral contraceptive pills. Some oral contraceptive pill causes regular bleeding on every fourth week, whereas some does not bleed by taking only 21 pills.

It is common to have irregular bleeding if you using oral contraceptive pills continuously. However, do not stop taking your oral contraceptive pills.

There are few causes of spotting such as missing or skipping the oral contraceptive pills, vomiting, diarrhoea or interaction with other medications. Vomiting, diarrhoea and some medications can cause poor absorption of the oral contraceptive pills into the bloodstream. This can cause the hormonal level in the body to fluctuate and causing shedding of uterus lining, leading to light bleeding.

It is also important to have protected sex if you missed any oral contraceptive pills. Pregnancy may cause irregular bleeding and stomach cramps.
