Medical Reasons To Avoid Sex During Pregnancy

Nhi.. Agar app relation rakhe to twins nhi hoga.... But plzz app 3-4 month tak physical relation naa rakhe...

Hi how is that even possible? You will not have ovulation when you are pregnant. So getting pregnant during pregnancy is just impossible. If you are pregnant and if there is no complications then you can have intercourse.
