What Causes Nausea And Vomiting Post Unprotected Sex?

Hey, I got sick last week after eating at a restaurant and was having diarrhea, and vomited once but all symptoms so I concluded it was the food I ate and it went away but at the same time i had unprotected sex so this week i am still feeling sick, nauseous all the time, hungry all the time, and every morning this week i wake up feeling so sick and have vomited but nothing to throw up but spit. Any smells make me nauseous, and when i dont eat, i get nauseous, and now i am constipated. I don't know what is going on and if a stomach virus last that long??

Hi Welcome to HEALTHCARE MAGIC..

I have gone through your query and can understand your concern...
Nausea & vomiting post unprotected sex could also be contributed to getting pregnant. Pregnancy cause elevation of progesterone hormones in body which could cause these symptoms like nausea, vomiting, morning sickness, increased food hunger etc.
However many of these symptoms could be caused by food poisoning or stomach infection as well. But morning sickness & increased hunger should not be there. In fact, stomach infection should cause decreased hunger & not feeling to be eating anything. Also stoppage of diarrhea or even constipation should mean that the infection you had is now treated.

You should definitely get your self checked for pregnancy by doing a pregnancy test. Pregnancy test is easy & could be done at home by using a home pregnancy test kit. Follow instructions on pack.

Refer to a physician, if you are not pregnant
Hope this information helps
