Uy, mama, I really think kailangan mo na talaga mag-check sa OB mo ngayon, especially with the pain and tightness you're describing. Hindi kami dapat mag-guess kung ano yan, kasi baka may importante na kailangan i-monitor. I know waiting na waiting ka na para maglabor, and honestly a few of us moms din nag-experience ng ganyan na nervous period, but yung araw-araw na sakit combined with the hardening, dapat ma-assess ng doctor mo mismo para sure. Go na sa clinic or hospital agad, okay? Better safe than sorry with labor signs. Rooting for you mama!
