You cannot get pregnant from pee on a toilet seat.
Pregnancy is not caused by pee but instead sperm that enters the Vagina.
If you simply sit down on a toilet seat with a males pee or urine and it gets into your Vagina you won't get pregnant unless sperm has actually entered your vagina.
You might get a UTI or other infection from the pee on the toilet seat but not get pregnant.
If you insert someone's sperm into your vagina then you can get pregnant if the sperm is fertile and you're fertile.
But there's no worry about getting pregnant from sitting on a toilet seat and getting urine inside of you.
Female pregnancy starts with fertilization, when a woman's egg joins with a man's sperm.
Fertilization usually takes place in a fallopian tube that links an ovary to the uterus.
If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
An egg must be released during ovulation and it must be fertilized by a sperm cell.
From a medical point of view, pregnancy begins when a fertilized egg implants into the wall of the uterus.
Pregnancy continues as that egg grows in to an embryo and then a fetus.
Pregnancy doesn't start the day you have sex it can take up to six days after sex for the sperm and egg to join and form a fertilized egg.
Then, it can take three to four days for the fertilized egg to completely implant itself in the lining of the uterus.
You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts.
This is the time of the month when you're most likely to get pregnant.
It's unlikely that you'll get pregnant just after your period, although it can happen.
There's also absolutely no way to get pregnant from kissing, no matter how much tongue is involved.
