How long have you been on the antibiotic?
Have you missed a period?
I don't think you are pregnant, but a pregnancy test is the only real way to tell.
As far as your throat symptoms, if you have been on augmentin for ten days, and not feeling any better, it's time to go back in and see what else is going on with you.
You may need a different anbitiotic.
At that time, you can surely ask for a mono test to be done.
It is always possible.
IF you do have mono, the best thing to do is get plenty of rest, plenty of fluids, and a good nutritious diet. If you are positive for mono, there may be some prescription anti-viral meds that they can give you, but this would be up to your doctor.
So, take it real easy. Listen to your body. Rest a lot.
