You likely experienced swelling following the injections that has since gone down. The swelling can last up to two weeks. I would recommend following up with the physician who performed your injections, as a touch up may be necessary to obtain the desired result. Keep in mind that a conservative approach generally appears the most natural. I hope this helps, and I wish you the best of luck.
After fillers it’s very common to have swelling for the first 2 weeks, once the area has healed you are able to see your final result. You may want to purchase another syringe if you’re wanting a fuller pout
The photos of your lips show that you definitely had injections. I agree that initially there is a great deal of swelling and you can not properly evaluate the results of the injection for up to two weeks. Since you don't see the results that you wanted I would recommend you going back to your treating physician. I have had many patients with bad experiences in Groupon. For the best results please find a board certified dermatologist with experience in injections.
