If i hadnt had my depo shot since october, but recently had sexual intercourse is there a chance i can get pregnant? my periods are still the same which consist of 4-6 days?

Depo shot ?'s: While it is advised that "Depo shot's" be administered every three months, there is variation in effectiveness, and pregnancy can occur without renewal of the progestin shot at the "three month" interval. Suggest using additional contraception until renewal of the long acting progestin shot. Ask your gyn physician about low dose oral bcp's.
