On antibiotics, had unprotected sex and only had a light period? I done a test but its negative, had sex 2 weeks ago and period was due last week.

It's possible... but if you have been ill, that may have caused your period to be off schedule. See what happens when your period is due next month, or you could wait another week and try another test at that time if you can't stand the wait. Be sure to follow the directions carefully.

Thank you for your help, as a 30 year old mother of 3 kids who are all at school I am hoping it is just illness or stress
