Chemical Pregnancy/Miscarriage

Victoria
Anyone experience this before or currently going through it? I would've been 3 weeks and I was getting excited to go to the doctor for all of the official stuff...but I had a dream last night that I was drowning in a sea of blood, screaming "Help me! Save me! I'm pregnant, somebody please save me!" When I woke up I realized I wasn't dreaming and there was blood in the bed. My husband keeps saying I must've not been pregnant and my period was just late despite the fact I'm extremely regular. I'm in a lot of pain and disappointed.
