There may be some bleeding with lip injections. Significant bleeding can be due to many factors. If you're concerned, I recommend following up with your injector about your treatment. It will take 1-2 weeks for final results. I hope this helps.
I agree that your upper lip may have been overinjected. Remember that in facial aesthetic proportions, the upper lip should be about 1/3 of the lip complex, meaning that the lower lip should actually be bigger. You can have the filler dissolved if you like. I would wait one week before...
