Early MC--what to expect?

Brandi
Happy Mothers Day everyone! We had a very slight positive on Friday, followed by 2 bfp's one with digital yesterday!  This morning I had some light bleeding which has progressed to very heavy with terrible cramping pain all morning.  I am fairly certain we lost the pregnancy.  I would have only been barely 5 weeks so very early still.  Just wondering if anyone else has MC'ed at this stage and what to expect? I'm going to call my Dr. In the morning! Thanks for any insight!
