Slowed down.

This is my first post on glow. I'm 5weeks & 6days and I noticed that I my frequent bathroom use has slowed down. Before I found out last Saturday I was going pee a lot & have been up until about 2days ago. I also had a sharp pain on my lower left side on Saturday, I don't have cramps or bleeding. Also have never had no morning sickness. I have my first doctors appointment next friday. Do you think I should be worried? Thank you in advance.
