Yes it can be normal some women bleed their whole pregnancy. I had spotting for over two weeks and my son is fine. If it's pink or brown you probably fine. But report this immediately to your doctor so they can check you. You could have a infection or just sensitive uterus. Don't mean anything is wrong with the baby.
If it turn bright red or you get bad cramps go to emergency room. What I'm telling you is information from my doctors I've been told a million times. When I bled and spotted there was nothing wrong with me or my soon.
Ive been spotting since i was 6wks and im about to be 13wks. Baby is healthy. Just watch for cramping and bright heavy bleeding.
