Replying to Contact Lenses

So this is my fourth day wearing contacts in my life. I've noticed that when wearing them (particularly inside) I get a little dizzy. Is this normal for first time wearers, or is my prescription wrong? I can see better with them than I can with my glasses, but my glasses I don't get dizzy. This is a trial pair of lenses. I would go to the doc but he's closed until the 4th for holidays. I have an appointment that day anyways.

Thanks.
