31.3 weeks as of now . Baby movement question .

no

My daughter is a very active baby. Very active . I noticed today/yesterday (31.2 weeks) my baby has been kinda active not much. But I also was working very very hard today so I could really keep up with movements. But now I am relaxing at home finally I noticed her movements aren’t as strong as usual. So my question is; is this normal some days or should I contact my doctor?
