26 weeks and 3 days and seems to b a decrease in baby movements.

Hey everyone. I am 26 weeks and 3 days. Up until about 3 days ago I had been feeling baby movements that were getting more frequent and stronger. About 3 days ago, it seems like the movement has become less. I do still feel an occasional flutter but mostly at night, not for sure kicks and punches throughout the day like I had been feeling. I am a first timer at this and I am getting really worried. I'm also diabetic and my sugars have been running a bit high lately but we r slowly getting that figured out. I am just unsure if I should b worried at this point. I have been feeling fine and have had no cramping or spotting or anything. Is it normal to feel a decrease in movement sometimes at this point?
