Uy, please go see your OB or go to the hospital agad, ha? Brown discharge after IE can sometimes need checking right away, and mas okay na marinig mo ito from your doctor rather than from us moms. Totoo, a few of us had different experiences after procedures, pero iba-iba talaga ang bawat katawan, kaya hindi dapat mag-assume. Get checked na para sa peace of mind mo, lalo na first time mo. Seryoso lang, better safe than sorry!
