When you switch brands of birth control to a generic, you are still getting the same hormones and the same dosage of hormones, the only difference is that the pills were made by different companies. If you have been on birth control for at least 2 months, it is still safe to have unprotected intercourse even though you are switching birth control. If you haven't been on birth control for at least 2 months you should use a back-up method, such as condoms, during the first week of starting your new birth control. If you want to be even safer, you could wait 2 weeks to have unprotected sex.
Yes, but it is not recommended. If you do decide to skip your birth control for a month be sure to use a back-up method such as condoms, to prevent pregnancy because all the hormones from the birth control will be depleted from your system. Skipping your birth control may also cause unwanted side effects as well, such as: late or irregular periods, or spotting or breakthrough bleeding. When you do begin taking you birth control again, be sure to wait at least 2 months before you have unprotected sex to prevent pregnancy. It is not good to skip your birth control or take frequent breaks either. If you do find that the pill is not for you, you should consult your doctor to find a method that is better for you.
If bc stands for birth control, then no, at least there isn't a case of this that I have heard of. If anything, it will make them bigger...birth control is full of female hormones, and these stimulate breast growth in many women.
No, however sometimes your hormones have a weird way of adjusting to the birth control. If you have not waited at least 7-30 days to have unprotected sex you may have become pregnant.
Condoms, IUDs, birth control pills, depot birth control medications (e.g. monthly, or quarterly), morning-after pill methods, contraceptive sponge, cervical cap, sterilization ... and the least effective method of contraception - the "rhythm method".
Probably praying is the least effective form of birth control.
The answer to the first part of the question is "yes." The answer to the second part is a little more nebulous; I'm not sure that this has actually been shown. It is undeniable that various hormones used in birth control pills are detectable in the water supplies of at least some locations, though.
You should use a backup method at least until the next month of pills.
You should consider taking birth control for at least 3 months to let your body regulate to the hormones and then you'll have a better chance of changing the time of your period.
If you mean the rythem method, it's a form of birth control that involves planning sex when a woman is least fertile, and it's not the best form out there. Plenty of people still get pregnant and there is no way of preventing stds
When you use birth control
It is when you start taking birth control pills immediately (the day you fill your prescription) rather than waiting until Day 1, Day 5, etc. of your cycle. This is only an option if you are certain that you are not pregnant. With the quick start method, you need to use back-up contraception for at least 7 days
