Pregnant?

Hope

My period is now a week late and I've been kind of nauseous. My breasts are not sore and I do not think I have any other pregnancy symptoms. I was also on two different antibiotics last month. Is it possible that I could still be pregnant or is the medication just messing up my cycle?

Ps. Maybe TMI, but I had unprotected sex once this past month but according to my calendar I was not fertile.
