16 weeks pregnant and uncomfortable lower back and abdomen pains??


I'm 16 weeks pregnant and the day started with some pressure in my lower back and abdomen, I've had it before though in the beginning and heard lower back pain is normal and I was in my first trimester, told my doctor was having lower back pain and if it was normal and she smiled and said yes, told me I'd probably want to use a lot of heat pads. then it went away and now I'm 16 weeks and today the pressure came back but it's sooooo annoying and uncomfortable, on top of that I naturally can't release gas correctly so ive always had gas pains since before pregnancy so it doesn't make it better now with all the gas pains on top of it ughhhh. anyone else suffering with uncomfortable pressure???
