Ay alam ko na yan na feeling, sobrang antsy na talaga by that point! Honestly, those crampy pains could be Braxton Hicks or early labor signs, the fact na may slight discharge and baby's head is engaged ay good signs na body mo ay nag-prepare na. One of my mum friends was in the same boat at 39+ weeks, and she just did a lot of walking, had spicy food, and relaxed as much as possible kasi stress talaga nag-delay ng labor sometimes. Pero since you're already this far along with these symptoms, best talaga i-follow up with your OB immediately para ma-check kung may progress na or if anything needs monitoring, they might even induce na depending sa findings, especially since you're past your due date range na. Kaya mo yan, mama!
