Could you be pregnant if are on birth control and just ended your period but for the last two days have been throwing up all night?

While birth control is usually very effective at preventing pregnancy, it is possible to become pregnant even while on birth control. If you are on birth control and have been experiencing nausea and vomiting, it is important to take a pregnancy test to rule out the possibility of pregnancy.

Some other factors that can cause nausea and vomiting include a viral infection (such as the stomach flu), food poisoning, or a chemical imbalance in the body. If the symptoms persist or worsen, it is important to see a doctor to determine the cause and receive appropriate treatment.
