I'm driving myself crazy, after MC last December, TTC the last few cycles, we finally got a positive reading. But I'm a little worried,  I'm 6 weeks along now, and a few times this week I have noticed a pinkish brown blood, not a lot, not even enough to fill up a panty liner. Didn't have this happen with both of the other pregnancies. Has anyone else had this happen? Is it normal? Thank you
