Hey mama! Brown jelly-like discharge is usually old blood, so it can happen kahit hindi ka buntis, sometimes it's just leftover from your period or hormonal stuff, lalo na if you're stressed or may changes sa routine mo. But since your last period was September at ngayon na, I'd really suggest checking with your OB to be sure, kasi mahirap mag-guess with these things at peace of mind is priceless, diba?
