how can i best support a trans friend who is pregnant

Ma

Today, 2 of my very close friends messaged me and told me that they just discovered they were pregnant. the friend who is pregnant is transgender, female to male and his boyfriend is a cis male- they were not trying to get pregnant but are keeping the baby! I’ve never had a friend be pregnant before nor I’ve ever known anyone in the specific situation (with the transgender stuff).

What I’m wondering is how I can best support them, things that I should do, things that I shouldn’t do with in regards to the situation? any advice or suggestions is very appreciated, i’m also talking to both of them and looking online i just figured there might be some people on here with personal experience with this situation or interesting perspectives! :)
