S.B.
She could still be pregnant. I spotted with both of my pregnancies. I down right bled with my son, but he's 15 and perfectly healthy.
Just get her checked.
You should be able to find out tomorrow whats going on.
If she's NOT pregnant, hopefully this will scare the tar out of her and she'll find better ways of protecting herself.
I wish you the best. Let us know what happens.
