Yes, very common. I used to get nose bleeds daily in my second pregnancy. They got worse the further along I was but the dr still said it's nothing to worry about.
I'm 37 weeks and still have blood in my nose. It's completely normal. Nothing to worry about. :-)
Swelling in your nasal passages is super common during pregnancy, so you may experience stuffy and sometimes bloody noses. Im 9wks as well and 3 times this week I had a little blood. No big deal :)
Don't worry. It is so common during pregnancy that the doctor would yawn if you told him about it. lol
