These may be perfectly normal. You are not a machine and something occur out of order.
caused from prenacy or birth control
No. If you get periods, you can get pregnant.
Women can take the birth control pills continuously without a break to skip the periods.
I had this happen to me also. I called my ob/gyn and found out I needed to be on a lower strength birth control. She changed my prescription and it's been fine every since.
Irregular periods are very common for women under 20. As you get older it should balance out. People say birth control helps..But i'm not positive.
While on birth control, your periods should last just as long as when you're not on birth control. Some women regularly experience 2-3 day periods while other women can regularly experience 6-8 day periods.
You shouldn't be taking birth control if you're not prescribed it. Birth control pills don't stop periods, they stop pregnancy.
Birth control is used primarily as a contraceptive, to decrease periods, and to decrease PMS symptoms
Yes, it's normal to have two periods in one month after you stop taking [hormonal] birth control - remember that periods aren't dictated by the calendar, but by your hormones. While on hormonal birth control your menstrual cycles are suppressed so that you don't ovulate, as you don't ovulate you don't menstruate, the bleeding you experience is a withdrawal bleed caused by the drop in synthetic hormones when going from active to inactive pills. Once off the birth control it takes time for your body to get back into a regular menstrual cycle.
There is no guarantee that taking birth control will stop you from having your period. You will most likely have your period anyway.
It will change your periods but they will still be there but you will just have them at different times of the month.
Hormonal birth control methods, including the pill, can decrease the amount of bleeding and cramping with periods. Some women use them for this purpose and not for birth control.
