Is it possible that I could be pregnant when on birth control pills?

Hi,

Welcome to icliniq.com.

I presume the birth control that you mentioned is about oral contraceptives pills. Sometimes, it is not uncommon to have spotting while you are on pills, especially if you miss a few of your pills and start taking the rest again. At times, it is possible to have some breakthrough bleeding even if you have not missed your pills. It is very unlikely to get pregnant if you take your pills regularly. But, if you do fall into the unfortunate group, who do get pregnant even after taking their pills regularly, I am afraid it is a concern as the incidences of pregnancy in abnormal sites (ectopic pregnancy) are common. So, I suggest you visit a gynecologist at the earliest to rule out the same. It might be a trivial cause of stomach upset like an infection, but we must rule out other serious conditions to be on the safe side.
