Discharged

Hello, I’ve been having brown discharge occasionally during my 2nd trimester.. everyone keeps telling me its fine. But today, when i went to the wash room to pee i found some blood and when i wipe there’s pinkish blood stain on it. But i dont feel any pain or anything. I’m just worried. Could it be im stress from work or sth? I’m a chef and i need to stands for long hrs, bending up and down to take things this and that..
