Thanks for writing to us.
Having sex just two days before the expected periods with an unbroken condom reduces the chances of pregnancy
considerably. If she has had her period on the due time after having sex then the pregnancy is ruled out.Vertigo
and pukish feeling are not conclusive of pregnancy. She needs to have a urine test done to rule out the pregnancy.
I hope this information has been both informative and helpful for you.
