Is it normal to get less likes/matches?

Hey, I (28M) recently joined Bumble, this is my first time with a dating app as I was dating for a long time, and because of this I don't really know what to expect and how those apps really work. I started using this app 3 weeks ago and have been to a few dates, but the numbers of matches and likes I'm getting are decreasing a lot, I had day with 8-9 matches and now it's never more than 2, unless I use those boosters. I didn't change my pictures or anything so I'd just like to know if this is normal? Or maybe should I update my profile from time to time?
