Contractions, pink discharge...

I'm 41 weeks today and finally started having contractions this night at 3 am (it's almost 9 am here now) they were very irregular at first but since around 6 they've been getting more regular but still 15-17 minutes apart and lasting for about 1 minute each. When I went to the bathroom just now I had some pinkish discharge on the toilet paper. Is this okay or should I go to L&D?
