Thanks ladies. I called this morning and she said if I'm still in pain and bleeding by the end of the day, then I should call back.. so I'm going to take some ib profen and drink some tea and hope this gets better. She said it could just be breakthrough bleeding, or a second period (on day 9!). I guess it depends on whether or not the pain goes away.
No matter what it is, I can't believe I'm still so messed up.
