Thank you ladies! Yes this is my second pregnancy.
It doesn't matter on the father's side for twins. It matters on the mother's side because it depends on if you release multiple eggs during ovulation or not.
Twins DONT actually skip generations... total myth. But I was super bloated at 9 weeks and now I'm truly showing. I'm sure you are too. Also if its your second pregnancy you tend to show quicker. I was comparing photos with my first born and I'm showing like 1.5 months earlier than my first (mostly bloat).
Twins skip a generation so it could be.
My ultra sound is the 5th ! My husbands grandpa is a twin.
When do you have an ultrasound? A lot of times you are just bloated during the first trimester so it's hard to say. But do twins run on your site of the family?
