Hi there. I spotted at the beginning of my pregnancy, and had full-out bleeds towards the end. My little guy arrived as healthy as can be, and on time too! Hang in there and take it easy. Definitely talk to your doctor, but, unfortunately, it's just a wait and see kind of thing.
spotting in early pregnancy can be normall. You indicated it is brown, which is old blood. make sure you call you doctors officee and let them know though. Drink lots of water in the mean time, and take it easy.
Yes it can be iv had spotting twice so far and I'm 8 weeks preg had a scan last week and everything was fine so fingers crossed hope everything goes well for u aswell :) x
