Bleeding after cervix check

I'm 36 weeks and last night I went to l&d; last night because I thought I had a leak and I was contracting every 1-3 minutes. So I was there for about 3 hours and I'm still only dilated 1cm (going on two weeks now) but as soon as I went home I went to the bathroom and noticed I was bleeding bright red blood. I've never bled after being checked before, and when I called they said it was normal, but everyone I talk to says that it shouldn't be bright blood, and even now when I wipe I'm still getting pink on the toilet paper
