Weight gain on antibiotics

Last Wednesday I got put on augmentin for a wisdom tooth infection. It has caused many side effects, I don't know if some of them are normal or if I should be worried. I have experienced:

Nausea (normal)

Dizziness

Head ache

Constipation

Fever

And heavy weight (7pounds in 3 days, and have not weighed myself since cuz I was so upset)

Are these symptoms normal or should I be seen by my doc again? I'm mainly worried that I'd gained so much and that I have had a fever for days. Did anyone else experience these side effects??
