Movements not so strong for 3 days.

Hey mamas so Saturday I had a very stressful day and I mean so bad where I was crying severely and heavy. My baby boy prior to this would move and kick strongly and now his movements are less and not as strong. I would feel his movements in my upper abdomen now I feel fluttery movements in my lower abdomen. Is it normal for baby’s to do this or something I should be worried. I called the nurse and she said it’s normal. My baby does move but not as strong. I am 26 weeks pregnant. Have anyone experienced this? I ask because Ive never had this before.
