28 weeks tomorrow

Tomorrow I’m officially 28 weeks . My baby had always been super active with strong kicks , punches etc . In the last two days, I’ve noticed they were barely noticeable and less frequent . I know kick counting doesn’t officially begin until “ tomorrow” but I’m really worried . Should I go to the hospital or is this normal ?

It’s my first child and in the last 24 hours my worry had just increased to the point where I can’t sleep. I’m laying on my side - drank water and still the same result .
