a break from TTC

So me and my fiancé are getting married in three months, we've decided to take a break from TTC until after the wedding and honeymoon, so roughly about 4-6 months, we both know it's the right thing to do because any of you brides/wives know how stressful the few months leading up to your wedding can be, but I can't help feeling a little bit sad. I 100% understand that this is the right thing for us both, and we're not using birth control so if it happens that's great but we're just not actively trying any more. Is it normal to feel sad even when you know it's for the best? I see all my friends having babies and I know our time will come, I just feel a bit down. Any advice would be greatly appreciated, if you've read all of this thank you 😊 x
