Keep an eye on baby's kicks , I am 27 weeks and hve days where baby is quite but if it last more then a day id go get it checked out just to b safe , and at that stage I would recommend walking over running cuz u could hurt yourself , take care:-)
Keep track of the kicks. Not to frightened anyone but with my first baby I didn't feel her kick as much as she would in the previous and when I went for my delivery her umbilical cord was wrapped around the neck. So just make sure the baby is actively kicking. Also careful with the running it can be dangerous to fall.
