Seasonique Amoxicillin I'm On The Pill, Recently Got Sick & Took Antibiotics. Been Nauseous For 3 Days Now. Could I B Pregnant?

I'm on the pill, recently got sick & took antibiotics. Been nauseous for 3 days now. Could i b pregnant? - seasonique amoxicillin

The pill is that I'm on Seasonique and I am only the second month, I have come half a month before my period. And the antibiotic amoxicillin was the first week and a week zythromax after 6 days.
I was just nausea or pain, hunger has increased ... none of these.
