I would see your doctor as soon as. It could be completely normal and nothing to worry about but it's best to be on the safe side
Bleeding can be normal....
I had heavy bleeding with my daughter for 4 months.. But my daughter was fine.
Another reason you can be bleeding is a STD.... (Not saying you have one) but if you are experiencing burning/itching/dark yellow pee or discharge get checked...
Wish you the best of luck.
As long as you aren't bleeding heavily or cramping it can be completely normal - that's typically what they say when you call before 8 weeks. If it continues you can go into the ER to get some tests done.
