When babies stop crawling out of you.How long after starting birth control does it become active?
Well, when you went to see the doctor they should have went over this with you.





It all depends on the birth control.





I would suggest a month since I dont know what type of application you are taking.





Pill takes 2 weeks to a month til it becomes effective.





Patch, doctors say 2 weeks, but I would stay a month to be sure.





The ring is fully effective as 5-7 days. I would still suggest 2 weeks to be sure.





BUT! Birth Control is not the only thing you should use to be safe. Dont be stupid, Birth control does not mean go to town without other things such as a condom.





Be safe. There are enough people in this world making mistakes and raising children when they are still young themselves. Watch out for only you.
about a week. Thats why they tell you to juse some other protection at the start of any birth control to reduce the risk of becoming preg. till the birth control takes effect.
Generally, about two months. But it differs sometimes by brand. Check the information packet that came with your prescription. If your not sure, and nervous, just second type protection.
It should be working. When I was on progesterone only pills its just took 10 days. You could just always call your gynecologist and ask or read the pamplet that came with your pills.
They generally want you to use a back-up form of birth control for the first full month. So, use a condom until you start your second pack.
I believe it's 30 days. You could do a search on your particular birth control or call your pharmacist and ask.
its active 1 month after you start...i just started a few days ago..your doctor should have told you that.......did she? hope i helped. =))
To be fully in your system and 97-99% effective- 1-3 months.
yeah my pill is active from day 1 however there should be instructions supplied if unsure you should ask your doctor
ummm we'll I think you have to go through your first back then it should be fully active.So that your use to that cycle.
