Skrg 36w ada keluar mcm egg white jernih + coklat sikit panjang dlm 4-5cm. Keputihan ke mucus plug?

Wah, that does sound like it could be mucus plug, sayang, especially with that jelly-like texture and the light brownish tinge, which is quite normal actually. Someone in my mum group mentioned that it can come out in pieces over a few days, not necessarily all at once, so don't be alarmed if more comes out gradually. The brownish bit is usually just old blood from the cervix softening and starting to efface, which is your body's way of preparing, but it doesn't always mean labour is immediately around the corner, especially at 36 weeks. That said, do keep an eye out for bright red bleeding, stronger contractions, or your water breaking, as those would need more urgent attention. It's really best to describe exactly what you saw to your doctor or midwife at your next visit, or call them sooner if you feel unsure, they can give you the clearest picture, dear.
