Pain/discomfort on my right side😩

This all started lastnight after waking up for a pit stop. Before actually going to the restroom after sitting up I suddenly felt a very uncomfortable sharp pain in my right side which slowed me down. I went to the restroom and while I was peeing I could feel the pain also in my lower abdomen! I brushed it off and went back to bed. When I woke up in the morning the pain was still there but I also notice that I didn't  feel my baby and I haven't felt any movements all day! The pain is still there. Debating going to the hospital because I have an appointment on Friday. 
I am 18+4 weeks. What could this be?
