You won't be pregnant now just after having sex a few days ago - pregnancy doesn't occur as quickly as that. It would take at least a week from intercourse. Having sex isn't going to make you sick - you most likely just have a bug or virus and starting feeling like that around the same time. It's just a coincidence.
It's possible, but very unlikely. More likely you're coming down with the flu or it's stress related. Also sometimes if the sex is rough or it goes in too far I have felt nauseated the rest of the day. So perhaps that could play in for you.
You may still be pregnant, consult a health clinic or a doctor perhaps? get a pregnancy test just incase aswell.
If you're like everyone else you're trying to figure out what the signs of pregnancy or pregnancy symptoms are and how likely they are to mean that you are pregnant. You can ask other people, you can worry in silence, but the best thing is to read through the categories and add up the signs. The more you have the more likely you are to be pregnant.
To help you out a bit here are some of the symptoms of pregnancy stages of during the early life;
Missed periods
Unusual cravings
Need of salty and sweet food types
Nausea or sickness (Can start early)
Extreme tiredness
Needing the toilet.
There are other causes than pregnancy for periods not arriving on time:
•Stress
•Being too thin
•Certain medicines
But if your period is definitely late and/or lighter than usual and you've been indulging in contraception-free sex, who are you kidding?!
"Going from a 34B to a 38C virtually overnight, going off tea and coffee and a strange metallic taste in my mouth"
Most pregnancy tests can be done from the day your period's due. They detect the pregnancy hormone human chorionic gonadotrophin (HCG), which rises rapidly during the early weeks of pregnancy, in your urine.
The NHS has useful info about pregnancy tests, if said pregnancy hormone is already scrambling your ability to think clearly
Some pregnancy tests are free aswell, if youre 18 and under..
Best of luck! Lots of love,
