Hormonal birth control does not always prevent ovulation so you could be experiencing ovulation pain. Also, since ovulation can happen that means fertilization can happen. In many cases when fertilization does occur, the birth control prevents the implantation of the embryo thus causing a very early abortion. You might want to research the abortifacent potential of whatever birth control you are using. If you are interested in preventing pregnancy without messing with Mother Nature and opening yourself up for risks such as blod cloths that could lead to stroke, and certain cancers that have been associated with BC you might want to research Fertility Awareness Method or Natural Family planning which are both very scientific methods of preventing pregnancy and can be 99% effective. Then you don't have to worry about aborting your progeny or the havoc these synthetic hormones can wreak on your body.
