I'm 2 weeks pp yesterday.
My sister recently had the same thing.
A couple of questions.
Have you been doing more work than usual? I mean had you been up and about and doing your chores like usual or were you still taking it easy?
Have you been taking any medications that would make you bleed more? Not sure if it's a coincidence,but the day she had her gush, she had taken some aleve which is known to cause slightly more bleeding. Which is what her doctor told her. Since her gushes stopped when she stopped taking her Aleve.
How long had you been sitting down? Sometimes after my child was born, I would be sitting down and would be able to tell my pad was dry, and then I would get up and blood would come out of me
That being said, I'd still call your doctor if I were you.
Well, it subsided so it must not have been anything.
I am so glad that you're back to normal. I had bleeding like that with a couple of my kids -- notably the last 2. I think it's if you're "overworking" sometimes the bleeding can increase for a short period of time.
Have a good weekend!
