I'm 6 weeks tomorrow. Not been to Drs yet. This last week or so I've been having this overwhelming (and bloody scary) feeling its going to be twins. It's really weird. I had a MC in July & DD is 18 months & in this pregnancies the thought didn't even cross my mind. Anyone else have this feeling & turned out to be right? What happens with twins? Do you just usually find out at 12 weeks at the scan?
