Hallow Dear,
Birth control by
contraceptive pills is governed by the continuous action of the pills taken throughout the cycle. Hence regularity in the consumption of pills is prerequisite for their success.
However, missing a single pill or so does not take away the protection against the
pregnancy. Missing up to 3 pills in a cycle is permissible according to WHO guidelines. When you miss pills like this, the ovulation calendar gets disturbed and you cannot rely on
fertility window.
Since you have missed three pills, there are good chances that you may conceive during this cycle. Wait for up to a weeks after finishing the pack of the pills if it is 21 pills pack, otherwise till you finish complete pack if it is 28 pills pack. By that time if you do not get menses, go for the tests for confirmation of pregnancy.
Pregnancy test on urine is to be performed on overnight first morning urine sample 8-10 days after missed period. Done earlier, these tests may give false negative results. Alternatively you may opt for
Beta hCG test which gives reliable results even few days before missed period.
If you are pregnant, you may opt for Medical Termination of Pregnancy which is very safe and effective up to 9 weeks of gestation.
I hope this helps you.
Dr. Nishikant Shrotri
