Can Plan B Change Your Cycle?

If you've recently taken Plan B or another form of emergency contraception, you may have noticed changes in your menstrual cycle afterward.

You might be asking:

"Normal ra ba ni?"

"Nganong nausab akong period?"

"Wala ba ni ni-work?"

First, take a deep breath.

Yes, Plan B can temporarily affect your menstrual cycle.

However, experiencing changes in your cycle does not automatically mean that something is wrong.

What Is Plan B?

Plan B is a type of emergency contraception used after unprotected sex or contraceptive failure.

Its primary goal is to help prevent pregnancy by affecting ovulation.

Because it influences hormones involved in the menstrual cycle, temporary changes afterward may occur.

How Can Plan B Affect Your Cycle?

After taking emergency contraception, some women notice differences in their next menstrual period.

This may include:

  • A period arriving earlier than expected
  • A period arriving later than expected
  • Changes in bleeding intensity
  • Changes in cramping patterns
  • Spotting between periods

Every woman's body responds differently.

Can Plan B Make My Period Late?
