About a week ago i got one wisdom tooth removed and a sinus lift. im on birth control and my periods late. is this normal?

Stress can cause it: Just because you take bcp, it does not mean you can not get pregnant. I would rule out pregnancy if you are sexually active. Stressful events can alter you cortisol in the body which in turn can affect you sex hormones.

No: Wisdom tooth removal will not affect your period directly.....But indirectly, ... If you were give antibiotics, they may have interfered with the effectiveness of your birth control pills. If you are sexually active, you should consider a pregnancy test.
