What is the name of the medicine that doctors give to ?

Question

make your period start within a few days after useing it?

Answer 1

Provera (a.k.a. medroxyprogesterone acetate).  You take 5-10 mg/day for 5 days. It creates a progesterone surge, which mimics the last phase of the menstrual cycle.  Then, when you stop it, the progesterone levels fall.  The body interprets that as a signal to start bleeding.

Answer 2

Answer 3

They can give you Plan B.

Plan B usually starts your period after using it because it is terminating a pregnancy by giving you a rapid spike of hormones. You can take it up to 120 hours after unprotected s*x.

Other than that regular birth control can help you have a regular period.
