Can I have lobster or crab?

Mandy • I am 34 pregnant w my second. A baby boy. My daughter, who is 4, was born a preemie and thus I'm a NICU Mom.
It's my birthday and my husband wants to cook me lobster or crab. I have not had any all pregnancy. I am 29 weeks. 
If it's cooked can I have crab or lobster considering they are shell fish? 
Any recommendations for a birthday dinner? 
I am 35- ahh!
