a small amount of jelly like discharge color is milky white

Mama, that milky white jelly-like discharge is usually just your body's normal hormonal changes during pregnancy, a lot of us experienced that too at different stages! But since you're noticing it at 33 weeks and wondering if labor signs are starting, I'd really suggest checking with your OB just to be sure, especially since every pregnancy is different and they'll want to rule out anything else. Water breaking isn't always the first sign anyway, so don't worry if that hasn't happened yet, you still have a few weeks pa. Fingers crossed everything's perfectly normal, but it's always better to have peace of mind this early, no? Hugs, mama!
