I agree with the other ladies.

There can be many reasons for your spotting. Yes, one could be an early indication of MC, but it could also be irritation from any Crinone or Pessaries you are using, irritation from DTD with your partner, or even a break-through bleed.

As I said, I had a reasonably large bleed early on, followed by an episode of pink spotting. It sounds like your HCG is doing ok so no harm in re-scanning until you are comfortable with any decisions you might need to wait.

Good luck!
