Brown spotting

lisa

This is probably tmi but I'm worried even though my dr told me not to worry but as many of you know that's hard to do during pregnancy .

I haven't had any spotting since I've been pregnant and all of a sudden I saw some brown discharge and now it's getting darker. And I've had constipation with bleeding. The discharge is dark brown. Mild backache but no cramps and just gas and bloating. Any other moms to be have this?
