Hey mama, those twitchy feelings and the jelly-like discharge sound like your body's getting ready for labor, a few of us had similar experiences near the end, it's usually just your cervix changing and losing the mucus plug, which is totally normal! The tightening (Braxton Hicks) is your body practicing too, so that's a good sign. Since you're almost full term and your check-up is just a few days away, I'd say monitor how you feel, if the discharge gets really heavy, you have bleeding, or the tightening gets painful and regular, best to call your OB na just to be safe, but honestly you're so close na! Excited na ba sa Sept 9?
