Question for all the mommas of multiples! Did you just have a feeling you were having twins? Have dreams of having more then one baby? Or was is just a surprise?...

I have a seriously strange feeling it's twins and had a crazy dream it was triplets! My mom keeps even saying twins as well as hubby.. my hcg levels were over 1200 on the 11th and I though I was around 5 weeks but I had a ultrasound on the the same day and they said I was extremely early like just after implantation early. I go back for an ultrasound on the 4th of October to know for sure. Thoughts? TIA
