How does a mini pill's effectiveness change if I miss doses?

Question

Hello doctor,

I started the mini pill in just over a month, and a few times, I have missed the pill by over three hours, and at least two days after three times, my boyfriend has ejaculated inside me. I am now four days late on my period.

Is this normal, or could I be pregnant?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

Mini pill are progesterone-only pills which work by thickening the cervical mucus, which will prevent sperm penetration and reducing the chance of pregnancy. Many articles and research have shown that using such pills has reduced unwanted pregnancy to 95-97%. Still, there are chances of three to five percent being pregnant. In your case, the pills will interfere with your ovulatory cycle, may delay or maybe early in your monthly period. These pills have been approved with a window period of twelve hours and are effective for twelve hours.

Generally, this pill should be taken without any break. If you are anxious, you can test your urine or test yourself using the pregnancy kit if it is legal in your location, which will make you relieve your doubt.

Pills should be taken regularly without any break or use of other means of contraceptives. I highly recommend using condoms as they are the best means of contraceptives as they will prevent sexually transmitted diseases (STD).

I hope this helps.

Thank you.
