Instincts?

Sarah
Hey ya'll! I'm pregnant for the 2nd time. About 6 weeks, haven't had first scan yet but will be in a few days. Wondering if anyone wants to share about there mama instincts on multiples? Something is just telling me there is more than one baby in here. I am not sure why, but it just feels different and am wondering if any one else has experienced something similar and found it to be true in later scans!?
