While I was lying in bed, my (luckily pretty small and skinny) 6 year old ds jumped across the bed and put the full force of one foot straight on my lower abdomen. I'm 23 weeks pregnant. It hurt quite a bit and still feels a little tender (happened around 30 mins ago). I have felt a few small movements from the baby since...do you think I should be worried? Obviously no access to midwife/gp today, plus we're staying with the in laws in the middle of nowhere. Any advice/words of wisdom very much appreciated...
