Period like cramps!

 I am 30wks 5 days today & this baby is just giving me a hell of a hard time! I am having so much pelvic pressure & pain! They feel like gas pain or period like cramps or both together.. I walk for a little bit i feel like the baby is kicking me down there! Everything hurts! With my other 2 children i had these at a later stage! Does anybody feel the same! Or should i be worried? Baby is very active so i am not concern about that part!
