Immigration..Entering in USA on H4 Visa while Pregnant

[supabhi]

Hi,

I am holding H4 visa. My husband went to USA on H1B last week.
I am currently 29 weeks pregnant and travelling from India to USA coming weekend. I am planning to be with him for at least 6 months.

Please let me know if there will be any problem in entering USA while pregnant.
Is there any chance I face problem at the time of port of entry?

Please advise.

Thanks!
