Is it normal to be scared for your first time?

Okay ladies so I just have a question... So I’m getting married this summer and my fiance and I have been saving ourselves for marriage, that being said I’m really scared for our first time. I’m not scared to have it with him, I mean he’s my best friend and I love him, I’m just really scared about sex in general. I went to small private schools and we never really had a sex Ed class and I don’t feel comfortable enough to talk to the non-virgin women in my life about it but is there anything I should know before going into it? I know this is an odd question but I just feel bad being so anxious about it, but I think its just because I never learned anything in school on the topic. Thank you for everything and please don’t come at me I just genuinely don’t know if it’s normal to be anxious/yeah idk.
