Question:
I have not started my period but i'm having a heavy dark yellow discharge and some brown jelly like stuff!
the first part explains it all!
Answers:
Yep, your going to get it soon. The "brown jelly like stuff" is probably the beginning of your period. The blood is old so its brown, and your period starts off light, so there's not a lot of it. It's completely normal, so don't worry about it. You'll probably get heavier bleeding in the next couple of days.
Hope I helped. = D
