This is the 3rd month i'm late. i have taken provera for 2 months and also clomid for 2. i am 7 days late and definitely not pregnant. would it be best to take the pill for 3 months to regulate. or provera again?

Pills : You need to regulate your cycle first before you start clomid ,so it is a good idea to start yourself on ocps to regulate the cycle

Depends: Clomid should only be used if you are trying to get pregnant and ideally while under the care of a physician. If you are not trying to get pregnant, Birth-control pills or Provera, taken for the same 10 days each month, can regulate your menstrual bleeding. Best wishes!
