Little late for implantation bleeding. I would call your ob were it me.
Some bleeding can be normal, but some is not.. Like kit said contact your ob or go to er to let them check you
Thanks.. Forgot to mention we had sex yesterday.
That could be why but wouldn't hurt to get checked
While that could be cause for less concern, bleeding should never be taken lightly imo. As I told someone yesterday never be afraid to call your ob. They are there to answer questions as much as measure your bell. They expect you to call Esp. When bleeding is involved.
