I got told drink a few sips of dr pepper and have some chocolate and see if baby moves because they love sweets! and it's cold lol but if not definitely go in!

But yes try cold water and then laying on your left side or just lay back relax and rub on your tummy

My hip hurt all the time when i was pregnant that sounds pretty normal. And sometimes your baby will have days in the womb when they arent as active. Does he usually move alot every single day? And if u were more active today than u usually are u might just not have noticed him moving? When i was pregnant with my first i worried myself like everyday with different things like little pains and was always worried he wasnt moving at times. Your first pregnancy will have u worried at times. But if u are concerned and feel somthing is off just give your doctor a call or go in no harm in going just to make sure

Drink cold water , and eat if baby doesn’t move you need to go to ER
