I got my 1st Depo shot on Dec 18. I had my last period on Dec 2nd-Dec 6th. I had unprotected sex on Dec 27. MycLadytimer app says that I'm suppose to get my next period on Dec 31. So the questions are: (1) How long does it take the shot to work? (2) is it possible that i can get pregnant because I didn't use protection? (3) When should i get my next shot? and (4) am i still going to gety next period on Dec 31 ?
You were protected for the sex. It takes a week for the shot to work. As long as you keep your shot current you have only a 0.3% chance of pregnancy. You don't need other protections. Hormonal birth control, like the shot, stop ovulation. Without an egg you cannot get pregnant. You might not get your next period, because the shot can stop your periods. You don't have to worry about your period coming with the shot. Count 90 days after you got the shot. This is when you would be due for another shot, the week before that. It would be in March around the second week of March.
