I definitely don't think you need to worry!

I bled at about 6 weeks, and it was quite light bleeding, pinkish, though it continued for maybe two days, and now I have a beautiful perfect 3 week old baby, also had a normal delivery and pregnancy was all normal.

In my very first pregnancy, I had a miscarriage. The difference in the type of bleeding with my miscarriage pregnancy, and my healthy one, is huge. With the miscarriage, I started bleeding bright red blood, and a steady flow. basically exactly like having my period. It was about a pad every two hours, and gradually progressed to one an hour.

So that's the difference between when the bleeding should or shouldn't worry you.
I hope all is well and you aren't stressing out of your mind!
