Twins!?

Hey ladies,

I'm just wondering if those who have had or are currently pregnant with twins had an intuition that they were. I am currently 9w5d and this pregnancy has been completely different than my first. I was able to pick up baby's heartbeat on my doppler at 9w1d and it was on my left side, today it was on the complete other side. I keep dreaming that I'm giving birth to twins, or that I have ultrasounds that show twins. There are quite a few sets of fraternal and identical twins in both my mom and dad's families. This is driving me crazy, and I still have a while before I'll have an ultrasound to know for sure.
