Yes it is effective on pre-cum (or semen), as well as regular semen.
You have to renew it every third month so no. It's not forever lasting.
Birth control is not a 100% way to stop pregnancy and your period makes those chances even worse.
Control measures are put in place to stop outbreaks and preventing re occurrences. An example of this is people getting the flu shot so they wont get the flu.
To change the f-stop on a Sony Cyber-shot camera, first switch the camera to a mode that allows manual control, such as Aperture Priority (A) or Manual (M) mode. Then, locate the control wheel or dial on the camera; rotating it will adjust the aperture value (f-stop). If your model has a dedicated aperture button, you may press that while turning the control wheel to change the f-stop directly. Remember to check the display to see the changes in aperture settings.
You can switch forms of birth control to what is most comfortable for you. If you would like to switch birth control consult your physician so that she/he can choose a birth control pill that is right for you.

The only way to stop an irregular period is to start taking birth control. Usually, you will become very regular when taking the pill and some people stop having periods all together when they go on the shot.
Everyone is different but a lot of women do stop bleeding altogether when they get on it, some have some bleeding, i didnt bleed at all when i was on the depo, but it depends on how your body reacts to the shot
One thing that can make the cruise control stop working is if the contacts are shot or have become corroded. It is also possible that the fuse is blown or that the module needs to be replaced.
You should assume that you no longer have protection from Depo Provera when you are late for the next shot. If you don't want to get pregnant, start using another birth control method at that time.
You stop being her friend.
