Is it normal to have bleeding during your first trimester?

Q: I'm 6-weeks-pregnant and I've had some bleeding. Is that normal, or should I be worried?

A: 25% to up to 50% of all pregnancies experience some type of "bleeding" during the entire pregnancy.  First trimester bleeding tends to be the most common and does not necessarily mean there is a problem with the pregnancy.  There are many reasons why someone may experience bleeding during a pregnancy - cervical trauma from a pap smear or intercourse, implantation bleeding a few days to weeks after fetal implantation into the lining of the uterus, loss of a twin early on in pregnancy but the remaining twin survives, etc.  All bleeding, however, should be discussed with your physician so appropriate follow up can be scheduled.
