I have two experiences with spotting, one not so good and the other is my current pg which is going well.

My first pg I was a bit over 6 weeks along, I got out of bed one morning and there was brown staining on my knickers like af was starting. Over 72 hrs it got heavier and I m/c that bub (was actually blighted ovum when I had the u/s).

This pg I had brown CM a week apart at 4.5 wks, 5.5 wks & 6.5 wks (1 - 2 spots per day). It just came out randomly like normal CM but was brown tinged. I spoke to my Ob about it after it happened the first time and he said the only thing that worried him about it was that it worried me. I had a scan at 5.5 wks which showed a healthy little yolk sac, then one at 7.5 wks which showed a healthy fetus and then I've just had my NT scan nearly two weeks ago and bub is coming along really nicely. I don't know why the brown CM was appearing.

So given what you have said - yours sounds like my current pg which is so far going really well.

It soooo hard not to worry but I really don't think both of our Ob's would have told us not to worry if things were really not looking good - Dr's don't give you false hope!

Hope you don't get any more spots. It's probably just bub snuggling in nice and tight.
