TWINS? a week behind??

Okay so long story…

I’ve been bleeding for one week. Spotting every day since I left for vacation. Before I left my beta was 1200. The doctors assumed I was five weeks due to my period. I got back yesterday and went to the ER today because of the spotting. I was told I have two sacks one measuring five weeks one day the other measuring five weeks. One has the yolk the other does not. I am officially freaking out my BETA is now at 15,000…

do you think it’s a problem that I’m measuring a week behind?..

I did have a chemical last month so maybe I ovulated later…? What do you guys think? Did anyone else experienced something similar?? I’m at a loss.

I’m so scared I could throw up..
