Impact of Withdrawal Bleeding on Menstrual Cycle After Stopping Medication

Menstruation after withdrawal bleeding?

Hello, I would like to ask, after stopping the medication for Medroxyprogesterone 21 tablets, I experienced withdrawal bleeding starting on the third day of the seven-day break, lasting about three days.
After the seven days, I resumed taking the medication on the eighth day, but after taking it for five days, my period has not yet arrived.
Will the withdrawal bleeding affect my menstrual cycle? Thank you.

Hello, you can start taking the birth control pill on the fifth day of your menstrual period.
It doesn't have to be taken at the exact same time, as taking it around the same time is sufficient.
As long as you take it consistently, it will be effective for contraception.
Generally, after taking the pills for five days, you should not experience any bleeding.
Wishing you good health!

More Info

When a woman stops taking hormonal contraceptives like the "美適儂21碇" (Mizhuan 21), it is common to experience withdrawal bleeding, which is a response to the sudden drop in hormone levels. This bleeding typically occurs during the placebo week when no active pills are taken. In your case, you experienced withdrawal bleeding starting on the third day of the placebo period, which lasted for about three days.
Withdrawal bleeding is not the same as a menstrual period; it is a result of the body adjusting to the absence of hormones that were previously provided by the contraceptive pill. After stopping the medication, it can take some time for your natural menstrual cycle to resume its regular rhythm. The timing and characteristics of your menstrual cycle may be affected by several factors, including the duration of time you were on the pill, your overall health, stress levels, and any underlying hormonal imbalances.

In your situation, you resumed taking the medication after the seven-day break, but you have not yet experienced your period five days into the new cycle. This can be concerning, but it is important to note that it is not uncommon for the menstrual cycle to be irregular after stopping hormonal contraceptives. Some women may experience delayed periods, while others may have lighter or heavier cycles than usual.
If you have been taking the pill consistently and correctly, the likelihood of pregnancy is low, but it is still a possibility, especially if you had unprotected intercourse during the week off. If you are concerned about the possibility of pregnancy, it may be advisable to take a home pregnancy test or consult with your healthcare provider for further evaluation.

In summary, withdrawal bleeding can temporarily alter your menstrual cycle, and it may take some time for your body to readjust after stopping hormonal contraceptives. If your period does not return within a few weeks or if you experience any unusual symptoms, it is best to consult with your healthcare provider. They can provide personalized advice and help determine if further investigation is needed to rule out any underlying issues.
Additionally, if you have any concerns about the effects of stopping the medication on your menstrual cycle or overall health, discussing these with your healthcare provider can help you make informed decisions about your reproductive health moving forward.
