Any advice will help.

So I've been to the hospital twice for cramping. They measured my cervix and said I find that it was at a 4 then four days later I went and they measure my cervix again and said it was at a 3.7. And said it was still okay. It's been a week and I've been contracting here and there with Braxton hicks. Today I wake up with severe cramping and a lot of pelvic pressure and the feeling that I need to pee but nothing  and back pain. I tried sitting and nothing helped so I tried walking and nothing helped I get home from work and go to the bathroom and wipe and I have a lot of bugerlike discharge (mind you I have been noticing more discharge than usual the past couple days). I was told I was at risk of pre term labor. Is this something I should be worried about? Or is it just me?? Some else going through this?
