no
You start to ovulate and get your period back and you can get pregnant again.
Yes.
It may take a few months to be able to conceive again, although some get pregnant very shortly after stopping birth control use. The number of times you stop/start taking birth control does not matter.
Nothing bad happens. You've established a new start day. From now on you'll start on this new day. No back up birth control method is needed.
Continue taking your birth control pills as scheduled.
If you've been on the pill for 10 days before having sex you should be OK.
You have to see your doctor and should've done it a long time ago. He will give you medicine to make it start again after taking tests.
About 3-4 days after the last pill.
Once you stop taking birth control, within 7 days of stopping it you will begin to ovulate and put yourself at risk of pregnancy. Before you re-start birth control, perform a pregnancy test. If the test is negative, you can re-start birth control. If the test is positive, see your Doctor for confirmation. When you re-start birth control, you cannot have unprotected sex until you've been on birth control for one whole month. So until this time you need to use a condom for 4 weeks.
You can start your birth control the Sunday after your period.
Sure can. I think you can use it when nursing, but check with your doctor first.
Taking the next birth control pill early does not impact effectiveness. Taking it late may.
