Is it normal for one side on my lip to look bigger after lip augmentation? (Photo)

Thank you for your photos. Swelling right after lip augmentation is very common, and this can give the appearance of "duck lips," asymmetry or both. You should see improvement over the next few days, and then see your final results develop over the next week or two. Cold compresses can help the swelling and should also help with any tenderness.

Thank you for sharing your excellent question and photographs.  It is not uncommon to have some stiffness and discomfort in the first day or so after lip filler treatment.  While a mild asymmetry is common with injections it sounds as if you may have had some increased bleeding causing yours.  This will resolve as your results mature over the next 2+ weeks.  Hang in there!

Yes, this can be typical following lip fillers. It can take 1-2 weeks for final results. I would wait a full 2 weeks before judging the results. If it is after the two week wait, you can have the filler reversed with hyaluronidase.
I hope this helps!
