Loose stools? 35 weeks

Tmi... I've been constipated literally since day 1 being pregnant. Then since yesterday I have been doing number 2 so many times throughout the day which is so unlike me. Ive read it could be a sign of labor, not literally but your body preparing to make room for the baby to come out more easily. I'm wondering if anybody else has had this problem? I'm 35 weeks + 2 days. Any info helps! I'm a FTM.
