NO, there's a small, very small, chance that you can still be pregnant if you get your period, however this happens rarely
There is a very slight chance. With pregnancy, there are always exceptions to everything.
As long as you're menstruating, there's a chance of a natural pregnancy. If you're not menstruating, there's no chance of a natural pregnancy.
You have a 1 in 2 chance of having a girl. No matter how many boys you have had in the past or how many girls you have had in the past, each pregnancy presents the opportunity to have a girl or a boy with a 50% chance. The sperm does not know that it had already produced ,say, 5 boys and needs to produce a girl for you and your partner. So with every pregnancy there is a 50% chance you will have a girl and a 50% chance you will have a boy.
Not at all, once periods start pregnancy can also occur if there is sexual activity, if anything it may be easier for a younger girl to conceive than an older one.
It lowers the chance
no, especially if there was no penetration
You don't. If there is a chance you are pregnant, take a pregnancy test. If not consult a doctor. Self-help is not appropriate here.
The chance of pregnancy following tubal ligation (burning, cutting, clipping, tying) is very small - but since our body's are designed to heal - it occasionally happens. The chance of this happening actually goes up slightly over the years. But it is still very rare. If you think you may be pregnant take a HPT, as the chance of ectopic pregnancy is slightly higher in a pregnancy following tubal ligation.
You are being extra safe and reduces the chance of pregnancy and STIs even more than before!
The chance of pregnancy is still present if sperm is released near the vagina, regardless of how quickly they exit. Sperm can still swim to reach an egg even if they are not ejaculated directly inside. It is always best to use protection to reduce the risk of unintended pregnancy.
You will have been advied by your doctor to wait 3 months. That gives you the opportunity to heal properly and give your next pregnancy the best chance.
