I know how scary spotting can be, but try not to worry and definitely call your healthcare provider tomorrow - s/he can probably get you an appointment and put your mind at ease. Good luck and have a Merry Christmas, if you celebrate that.
I had a M/C between dd2 and dd3 and that pregnancy had zero symptoms. When the spotting started it progressed to bleeding within a day, then more bleeding. So it was pretty apparent from the start.
I hope that the spotting is brief and not problematic for all of you!
Spotting has increased today, and I feel a little crampy. Haven't had this in any of my previous pregnancies, so I still don't know what to think. I was feeling pregnant the last couple of days (belly starting to bulge a little).....my m/w appt isn't until the 15th, so I have a while to wait.
