Never be afraid to go see he/she... I stayed pretty much at the doctors office everyday for the weeks prior to my miscarriage.
Bleeding does not always mean you will have a miscarriage. You do need to go to the doctor and be closely monitored. I started bleeding and things went downhill pretty fast for me but my sister in law bled the whole time and she didnt so each person is different. Just go to your doctor. With your fluid getting low you may be high risk and need monitoring closer but when in doubt.. GO SEE YOUR DOCTOR!!!
I also experienced mild bleeding at first, but unforunately at 13 weeks we lost our baby. Monitor what is happening closely and don't hesitate to go to emergency if you get any pain or bleeding gets heavier. You might be ok, from other forums I read the other day, it's not always a bad sign. But please get to the emergency room if it continues.
