Baby movements increase after smoking

Hi all Canna mommies, I want to know if you experience more and stronger movement or feel cramps or contractions after smoking weed? I feel like my baby kicks harder and repetitively (really low) after smoking and it freaks me out! The 1st time I felt it I thought maybe they were contractions but I don't know what those feel like... 22 weeks with my 1st baby. So far my doctor says everything is fine and my baby is developing on schedule. He moves all the time even when I don't smoke.
