TMI bowel movements

35 weeks and for the past week or two I can FINALLY poop again. However, it is becoming more frequent and slowly getting looser each day. I know they say loose stools is a sign of labor going to start but being only 35 weeks I’m kind of worried of that happening being still early. Anyone experience loose stools then labor? How long before you actually went into labor? I left a message for my OB asking if I should be concerned or not yet. Definitely enjoying the relief but now I’m all paranoid this baby is going to be here sooner than later.
