If you have a Nurse's line, call and talk to them about what is happening. For the most part, it's something you kind of have to wait out until your doctor will see you. There isn't much you can do but rest as much as you can. I'll pray for you and for everyone else going through this. I can relate to you as well. I miscarried at 6 1/2 weeks last August and now just found out I'm pregnant (only 4 wks 6 days). I am very excited but also scared because of my last pregnancy. I hope everything is ok for you!
some light bleeding/spotting in early pregnancy, while scary, is normal-as long as it is not accompanied by cramping. Of course, this is something that you will want to talk to your dr. about as soon as possible, however, all you can do is try to relax and wait...sorry.
