Can I take a contraceptive injection immediately after stopping the contraceptive pill?

To @Anna:
The injection can be done in a gynaecologist's office - by a nurse, midwife or gynecologist.

Good morning
Who should give the contraceptive injection? And where is such an injection made?

I'm using Vines pills, I still have 3 pills left and I'm taking the last pill on the day of my first period, and the gynecologist said that I should take a contraceptive injection on the first day of my period (I'm switching to injections right now). Can I take a pill and an injection on the same day?

To @Julia: You can start taking your Slinda tablets on the day you need to inject again. Contraceptive protection will remain preserved, so after the change it is not necessary to use additional contraceptive methods.

And what in the opposite situation as the injection wants to go to slinde tablets, I have to do the injection on July 28 another day as if I had to do an injection take 1 tablet of slindy?

Yes, you will be protected. If the injection is given for up to 7 days (break/use of placebo tablets), no additional protection will be necessary.

And if I take vibin mini pills and they have 7 placebo tablets and how do I do a contraceptive injection on the 7th day of placebo, will this injection protect me immediately from pregnancy?

To @Anna: Yes, you can start using injections on any day of placebo tablets.

And I can take 3 placebo tablets and on the 4th day where should I take a placebo I will take a contraceptive injection?

To @Karolina: You can take the injection both in lieu of placebo tablets and after you stop taking them. If placebo tablets are missed, no withdrawal bleeding will occur.

But the injection should I come instead of placebo pills? After taking these 4 placebo pills?
