What Are the Side Effects of Camrese 91 Day?

Camrese 91 Day is an extended-cycle birth control pill that gives you only four periods a year. Like all hormonal contraceptives, it can cause side effects — but most are mild and tend to improve after the first few cycles. Here's what you need to know so you can feel confident about what's normal and what's not.

Common Side Effects

The most frequently reported side effects of Camrese 91 Day include:

• Breakthrough bleeding and spotting — This is the most common side effect, especially during the first 91-day cycle. Your body is adjusting to having fewer periods, and irregular bleeding is expected. It usually decreases with each cycle.
• Nausea — Taking your pill with food or at bedtime can help reduce nausea.
• Headaches — Mild headaches are common when starting hormonal birth control.
• Breast tenderness — Your breasts may feel sore or swollen, especially in the first few weeks.
• Bloating — Some water retention is normal as your body adjusts.
• Mood changes — Some people notice mood swings, irritability, or feelings of sadness.
• Weight changes — Small fluctuations in weight are possible, though significant weight gain is uncommon.
• Decreased sex drive — Some people experience a lower libido on hormonal birth control.
• Acne — While Camrese 91 Day can improve acne for some, others may notice breakouts initially.
• Abdominal cramps — Mild cramping can occur, particularly around the time you take the yellow (low-dose) pills.

What's Normal in the First Few Months

If you've just started Camrese 91 Day, give your body time to adjust. It's completely normal to experience:

• Irregular bleeding or spotting for the first 1-3 cycles (up to about 9 months)
• Mild nausea that goes away after a few weeks
• Slight breast tenderness that improves over time
• Minor mood changes as your hormones stabilize

Most of these side effects are temporary. If they haven't improved after three full 91-day cycles, talk to your doctor. They may suggest switching to a different formulation. Check out our guide on alternatives to Camrese 91 Day if you need other options.
