Did you just know?

So last night my mother in law texted me out of the blue saying "time for twins huh?" ( she knows I'm pregnant) she is a twin, so we know it's possible. Plus I'm over 30 which increases your chance of twins.. I haven't been able to get it out of my head. How many of you just knew? ( I'm 4 weeks 3 days) first u/s scheduled for August 7th
