5 weeks and 5 days and bleeding

Just started bleeding last night (Fri the 13th... Really?!!).  I'm freaking out here big time.  I called the Doctor on call that evening and he told me to rest this weekend.  Ill need to make an apt on Monday.  My 1st pregnancy was a breeze.. Never bled.  I know you can bleed during first trimester but like how much blood?!  Everytime I wipe theres blood but so far nothing on the pad.
Anyone else have this experience?!? How was the outcome?
