What to Do When Your Period Starts with Birth Control Pills Left? - Obstetrics and Gynecology

When you are on birth control pills and your period starts while you still have pills left in the pack, it can be a bit confusing. However, it’s important to understand how birth control pills work and what steps to take in this situation.

First, it’s essential to recognize that birth control pills, particularly combination pills, are designed to regulate your menstrual cycle. They typically contain hormones that prevent ovulation, thicken cervical mucus, and thin the uterine lining. When you take the pills as directed, you can expect a withdrawal bleed (similar to a period) during the placebo week or the last week of your pill pack.

In your case, since you are on a 21-day pill regimen and your period has started while you still have two pills left, here’s what you should do:
1. Continue Taking the Pills: You should continue taking the remaining pills in your current pack as scheduled. This means you should take the last two pills even if your period has started. Stopping the pills prematurely can disrupt your cycle and may lead to unexpected bleeding or spotting.

2. Start the Next Pack on Time: After you finish the current pack, you should take a seven-day break (if your regimen includes a break) before starting the next pack. If your pills are designed to be taken continuously without a break, you would simply start the next pack immediately after finishing the current one.

3. Monitor Your Cycle: It’s normal for your cycle to be a bit irregular when you first start taking birth control pills. If you notice significant changes in your bleeding pattern or if your period becomes excessively heavy or prolonged, it’s advisable to consult with your healthcare provider.

4. Consult Your Doctor: If you have any concerns about your bleeding or the effectiveness of your birth control, it’s always a good idea to reach out to your healthcare provider. They can provide personalized advice based on your medical history and the specific type of birth control you are using.

5. Understand Breakthrough Bleeding: Sometimes, breakthrough bleeding can occur, especially in the first few months of starting birth control pills. This is usually not a cause for concern but can be annoying. If it continues or worsens, your doctor may suggest a different formulation or dosage.

6. Consider Other Factors: If you’ve missed any pills earlier in the cycle, that could also affect your bleeding. Make sure to take your pills consistently at the same time each day to maintain their effectiveness.

In summary, continue taking your remaining pills, start your next pack as scheduled, and keep an eye on your cycle. If you have any further questions or concerns, don’t hesitate to consult your healthcare provider for guidance tailored to your situation. Remember, effective communication with your doctor is key to managing your reproductive health effectively.
