I feel like in going crazy


We are expecting twins, i found out at our 7 week ultrasound appt. We were both shocked as twins do not run in our families... well, here i am 9 weeks along and i am starting to get nervous telling people we are having twins.

My friend experienced "vanishing twin" her third pregnancy and now i cant stop thinking about it! I get fixated on things every now and then.... im not sure if because i had such a early ultrasound i fear one will be gone the next time or i am still in shock.

Does anyone else think of this and worry as well?
