Yes, if you are sexually active.
There are about 12 different kinds of birth control pills. if you missed one you should immediately start using an alternate form of birth control and call your obgyn/clinic and ask the doctor/nurse about what to do.
You can go on birth control when you have herpes.
Yes
No. Actually when starting birth control it can cause your periods to be irregular at first.
No, you should continue to take the birth control and then go and see your doctor about it and address any and all concerns about the medicine with him or her
Over time the pill regulates it and can make it shorter and lighter. Once you stop the birth control pill, you can expect to go back to your previous menstrual pattern.
I don't think that should be happening, I suggest you go back to the doctor or clinic.
Generally birth control pills take a month to go into affect, so you should wait at least a month after switching pills.
i think youn should go to a doctor
Yes that is still normal, in most girls, the pain should either go away or just hurt less. Some girls go on birth control for that exact reason, so it is normal for you to have stomach pain on birth control
You should act like you have never taken birth control before as far as protection goes. Start taking birth control just like you did for the first time you started taking birth control (if you have forgotten, read the instruction pamphlet with your pills) and use a back up contraceptive (condom) for the first 30 days before having sex without a condom.
When you take the birth control pill, you can expect shorter and lighter periods. When you stop the pill, your periods go back to their natural length and heaviness of flow.
