What Can Cause Frequent Brown Spotting in Early Pregnancy?

Dear Midwife,
I'm really hoping you can help me understand what's going on. I am 8 weeks 2 days pregnant (our first). I've been getting brown spotting here and there but nothing major. They did an ultrasound last week -- everything was great, saw a heartbeat and measured fine. This week I got another ultrasound and same thing -- the baby is growing well, and heartbeat is strong at 163. I have been getting this brown spotting now for the past three days, and the nurse told me if it's brown (which it is -- sometimes light, sometimes dark) it's "old blood" working it's way out.

My question is where does the "old blood" come from and how much of it could there possibly be in there? I haven't had an internal ultrasound or a pelvic yet. They have me coming in at 10 weeks for that. I'm concerned. But every time I call the doc's office they say it's normal and not to worry.

I've had a history the last year and a half of getting my period twice a month while on the pill and they never figured out why. I'm concerned that this won't work either. I'm happy to believe the old blood theory but if it keeps coming every day (it's usually only when going to the bathroom) then it will be worrisome.


You may have a mild infection on your cervix, or you may be one of those unfortunate women who spot all through their otherwise perfectly normal pregnancies. If there were a serious problem with the baby, they probably would have seen it on the ultrasound, so hopefully all is well. Good luck!
