My period is 2 weeks late. I am very regular and never miss a period. I took a pregnancy test 1 week ago an dit was negative, so started my next cycle of birth control pills. I am now having pains in lower abdomen. Could I be pregnant?

If you have been having sex, of course there is always a chance, birth control pills are not 100 percent. But of course it is a better chance at an infection or another issue but there is a chance
