Depo to pill

Amber

Im due for another depo shot on the 12th but it’s messing with my mental health so bad that I can’t do it. So I’m going thru Nurx to get the pill. Im not sure if I’ll have it by the 12th so there might be a gap in BC. Can anyone tell me how long I should take the pill before safely continuing sexual activity?

Btw I have googled it and can’t find what I’m looking for
