Should I go to the hospital and get checked?

Britni • Pregnant with our second baby!! We just had to have another since the first one turned out so perfect😍 We both want a large family, a lot of children💕
I called my nurse line and left a message yesterday during office hours and never got a return call... I had pretty frequent contractions yesterday, more than usual... Woke up with tons of lower back pain and aching legs and pelvis... It hurt to walk or move really. And I've been leaking a very thin fluid with white in it. I think it's weird I didn't even get a call from my doctor saying we aren't worried about your symptoms... Should I go to the hospital or just don't worry about it till my appointment on Friday afternoon? I am 35&1 and this will be my second baby. First time I was induced sue to an IUGR so I'm not very familiar with going into labor naturally
