Each baby is about the size of a large cabbage.

Here’s an ultrasound video of what you might see at 30 weeks pregnant with twins:
If Your Twins Were Born This Week
Your twins are early preterm and the odds of survival are better than weeks past. However, twins born during the 30th week still risk major medical complications. They could spend weeks, if not months, in the NICU. Twins born this week average a hospital stay of about 36 days.
