Movement question.

Hi all. FTM here and currently 25w1d. I have an anterior placenta and just started feeling kicks in my 23rd week. For all of 24w I felt her kicking a ton throughout the day, high and low. I and others even started being able to feel her kick on the outside. Yesterday morning I felt her but since then I haven’t. Last night I thought I felt a kick or 2, but not the regular way. This morning I think I felt 1 but not positive. When should I worry? I know kick counts should really start until 28 weeks. Could she just have had a lazy 24 hours or be hidden completely behind the placenta? It’s only 6am here but I am currently eating chocolate and ice Cold water trying to see if that helps. Thanks all!
