Is spotting during the first trimester normal?

Yes. Spotting during the first trimester is very normal and sometimes spotting may go along with mild cramps. Many times the spotting is caused by your uterus growing and breaking small vessels for more room. However if you are having spotting which continues to bleeding and filling a maxi an hour for 3 hours along with heavy cramping there is a great chance you are having a miscarriage. When you are in this situation Dr's advise on an immediate call and will have you come in, even though there is nothing they can do to stop the miscarriage, before or during, if there is a problem with you...i.e bleeding wont stop or anything more problematic happens they can help you.
