35weeks 3days 3cm 70% effaced

I have been having mild contractions for the last two days and loose bowel movements and some mucous when I wipe. I had a appointment today. I'm 3cm 70% effaced this is my 5th pregnancy. My contractions haven't seem to stop at all but become a bit more noticeable. Hoping nothing happens when my husband goes to work. I don't want to make a trip to LD for nothing.
