If they are expired by a few months or weeks then they will probably mess up your cycle for the next month.
If you leave in Mirena after it's expired, you could get pregnant. Use an alternate method of birth control. If you are seeking pregnancy, have the IUD removed.
i dont think so
Birth control suppositories are one of the least effective methods to begin with. Withdrawal is more effective than spermicide used alone. Consider getting some condoms and throwing out the expired suppositories.
Like all medication, when it expires, it becomes less effective (and increases in its ineffectiveness as the time goes on). It's not easy to give a percentage as to how effective compared to non-expired pills, but if using expired birth control is your only option, I would use it with a condom or some other non-hormonal birth control to make sure you don't get pregnant. Otherwise, the likelihood of pregnancy will increase.
Nothing
If the birth control fully works, there won't BE a fetus, birth control will do nothing about an impregnated egg or the baby that it will result in.
I wouldn't. If it is expired it will not work correctly and could be very bad on your stomach.
Birth control loses all of its effect the day that you stop using it.
You can get pregnant
There is no increased risk of pregnancy if you miss the non-active birth control pills.
Yes. In the first few months of being on birth control, this happens frequently, and it fades as you continue to use it.
