Celtic - i hope everything works out for you. Have you had the u/s yet?
I had similar thing, went and to the first dr in Melbourne that could see me (i was ment to be flying from Melb to Perth when it happened) and he told me that it was a m/s as well. I panicked. But, when i finally got an u/s done, everything was all ok. baby was there heart beat was going strong. I was 5 weeks and 2 days. They did an internal u/s which showed the baby. Tell your mum, or someone, to be with you today.
I have been where you are now, and you need someone to lean on.
Big hugs to you, and will be thinking of you.
