If there was no penetration, you most likely aren't pregnant. Precum even lessens the chances, since it can rarley get you pregnant.
Yes, sperm are present in pre-ejaculatory fluid. Hence it is entirely possible for a woman to become pregnant even if the man does not actually ejaculate. If you want to avoid pregnancy, any contact between genitals (up to and including penetration) should only happen with protection.
If it was oral sex then you can't be pregnant
No, semen is just the transporter fluid, it's the sperm that gets you pregnant.
No, women cannot get pregnant from another woman's vaginal fluid. Pregnancy can occur when sperm fertilizes an egg, and this typically requires semen from a male partner.
What exactly do you mean by no penetration? If you mean he never put his penis into your vagina, then no, it's not possible for you to become pregnant. However, pre-cum CAN contain sperm, so it's possible to become pregnant from that. In any case, taking birth control screws up your period. Not only does it sometimes change the dates on which you get it, it also shortens the duration of it. If you didn't get yours right on time, I'm sure you're still fine. Just give it a little time.
There is only one way to get pregnant (apart from artificial insemination) and it does not involve drinking water or any other fluid of any description.
Depends on "what" second. If any fluid from the penis was present (pre-cum/clear fluid or cum/whitish) then pregnancy is possible.
The hymen cannot be broken, it is not made of glass, it can stretch or tear whenever there is penetration - but normally only if penetration is rough or forced. Outercourse thus cannot tear someone's hymen as there's no penetration involved.
That would be the semen which is the transporter fluid for the sperms. They can only be separated from each other in a lab. And no, it's the sperms that make you pregnant.
Penis size has nothing to do with getting pregnant. Only required is a good quality of semen and sex with pleasure, and the most important is the timing of penetration (near ovulation period). There are thousands of people having short penis, leading a perfect family life.
The difference between a full penetration weld and a deep penetration weld is the depth at which the metals being joined are actually joined. A full penetration weld is a slight puncture only to heat the two metals and join them. A deep penetration weld is a deeper hole puncture that is held and a metal wire is melted to join the metals.
If you are taking your birth control properly (same time ever day/night, not missing pills, not using antibiotics, etc) and use the condom properly it is HIGHLY unlikely that you will but there is a small smidgen of possiblity that you could get pregnant.
