Oh, I understand how worrying it can feel when you notice a change like this, especially as a first-time mum, it is completely natural to be concerned. Movement patterns can sometimes vary from day to day, but since you mentioned baby was more active before and now feels less so, I think it would be wise to check with your doctor or midwife just to have peace of mind, sayang. Please do not hesitate to call your klinik or go to the hospital if you feel unsure, because they are always there to help and your concern is very valid.
