Suggest Remedy For Delay In Periods

hello,Im 26 years old I'm from lebanon. i was expecting my period on 28 July but it did not came and as the culture here in lebanon forbid the sexual relation i have no source to ask. i did like 5 pregnancy test the last one was last week and all of them are negative. i went to the doctor but i did not have the opportunity to ask him as my parents were with me. the doctor game lutenyl and im taking it since 3 days. I really need to know if im pregnant and what to do. plus i have a vaginal pain the same as i will have my period. thank you
