you need to get the shot asap when you start your period.its best if you get it the day you start your period
If you use the depo shot correctly it will work automatically what I mean by correctly is getting the shot during your cycle I would suggest getting the shot during the first day of your period :)
i have been on the depot shot for three months my period did not come the fourth month what should i do
The first shot of Depo Provera is usually given during or a few days after the start of a menstrual period.
Can take up to a year for your period to start.
i was on my period when i got my shot and it lasted for over 14 days. After it ended i havent had another period for over a year now.
it is normal because i had that happen to me a couple of times while i was on the shot so its normal to have one
The two reasons you take your first short during your period are that you know you are not pregnant, and the shot prevents you ovulating in your next cycle. The shot can be given later but you should then use a barrier method of contraception for 7 days. This should all have been explained to you by the person giving you the shot. It appears you did not have sex after your period so you were not pregnant but as you had the shot so late in your cycle you would probably have ovulated. You then went on to have sex. YOu would have been unprotected by the shot as your own hormones would have been already activated. The problem is also that while on the shot many women do not have periods so if you do not have your next period it may be because of the shot, or you may indeed be pregnant. All I can suggest is that if you don't have a period when it is due that you wait a week or so and take a pregnancy test. You cannot rely on other signs that you are pregnant as the effects of the shot often mimic those also. Good luck
you should ask your doctor
as slkg fjkld
it should start in about 35 days, if not a pregnancy test should be administered.
Most people on the depo shot do not get their period. i was on it for about 7 years and only had my period for about the first year
i personally think its best if you wait ten days since your last shot! ;) x
