Turning 21 and pregnant

Kinda a bummer since when your 21 your "supposed" to be going out and getting drunk but I'll be 5-6 months pregnant. What can I do for my birthday? I wanted to go to the club but my mom was like ew no. But I've never been to one and no I wouldn't drank just have a good time with friends and some family and my boyfriend. Idk a lot of things I can do while pregnant and turning 21
