Do I go in?

So I started contraction last night around 7 they were strong but not consistent. I was able to go to bed around 11 but woke up around 1:15 with cramps. Went to the bathroom and had pinkish/red in my toilet paper and toilet. I started tracking my contractions they are about 6 minutes apart lasting about 25 to 30 seconds. Should I go in? Waiting for doctor to call me back?
