Fetal Movement @ 28 weeks

Hi!

I am 28+4 on my first baby! Been feeling my boy move now for a month or more but I’m unsure if what I am feeling is “normal” for this stage. I feel him every day but it never really consistent on the frequency. Some days I can feel him a lot with big kicks and lots of belly movement and then other days I’ll just feel small little movements or hardly anything at all. There’s been no issues to date with my pregnancy. I see my OB for the first time in a couple days so I’ll be sure to mention my concerns to her....just wondering if anyone had any insight as I have myself drove a little crazy worrying!!
