My friend?

My friend had sex a few days ago and it was her first time and she complains now that she feels as though shes cramping or sick to her stomach like when she is on her period but she has already had her period a week before sex. Any idea as to what is wrong?My friend?
As it is sex first time so this type of feeling can happen. Do not worry, drink enough water. Hope everything will be alright. And do not do sex again before you feel alright.
I think she's pregnant. You should buy a pregnancy test.
STD maybe or she could be pregnant.....she should go to the doctor's office.
Don't worry it's normal.May be she has not used tampons.The thing may have been long and big and nothing of that size has gone inside her. She will get used to it.
