Bleeding during first trimester?

I recently found out I was expecting,about a week ago and I have yet to see a doctor,im unsure about how far along I actully am,im guessing anywhere between 7 weeks to 10 Weeks.Im young,and scared,this is my first child.the feeling i get knowing im expecting is more joyous than most can imagine,Im more attached than I should be this early on maybe.I heard from many women that bleeding is normal,as long as its light with no cramps.Mine is moderate,to light,with no cramps,but its happening every day almost rutinely at the same time.it scares me,the last thing I want is to loose my little sea monkey.Any advice on this would help so much,should i be as scared and lost as I fee?or should I relaxe and not worry about it,just enjoy the pregnancy.I have scheduled a doctors apointment but i cant get in till april 18th,should I just pay extra and take a trip to the ER.i dont much have a mother to talk to about these things,any help would be wonderful and much appreciated.thank you.
