Hi, I Had A Baby In September And I Also

Hi, I had a baby in September and I also had my tubes tied and burnt off, lately I have been experiencing some stomach tenderness when i lay on my stomach it hurts and yesterday (as if I was pregnant and pee'd my pants) I gushed something out as I was walking when i went to the bathroom it was blood, color was light. I have been feeling faint at times that last for a few seconds.
