Ok so I I started feeling nauseous about an hour and a half after sex. Am I pregnant?
If you’re worried that you became pregnant from the sex you had and it was the pregnancy that made you nauseated, rest assured. Pregnancy doesn’t start just an hour and half after sex, so you wouldn’t start feeling pregnancy symptoms that quickly.
Here’s how pregnancy happens: sperm from semen or pre-cum travels through your vagina and cervix, into your uterus and fallopian tubes. The sperm meets an egg, and then the combined sperm and egg implants into the wall of your uterus. All of these steps can take a week or two to complete. When (and if) that happens, your body starts releasing pregnancy hormones, which won’t cause symptoms like nausea until enough of it has built up in your system — another week or two, if at all.
The only way to know for sure if you’re pregnant is to wait for your period, and if it doesn’t come on time, take a pregnancy test. And if you’re not trying to get pregnant and you’re not already using birth control, an hour and a half after sex is not too late to take emergency contraception. Emergency contraception is a safe and effective way to prevent pregnancy after unprotected sex.
