good way to announce pregnancy in wedding speech

I'm currently 9 weeks pregnant but of course not showing yet. At least not that other people would notice. 

I'd like to announce my pregnancy to our family and friends during my speech because I feel like it'd be weird not to. We've been ttc for over a year and I feel like I deserve a bit of the spotlight 😊

What's a cute way to do it? I figured I could have everyone raise their glass at the end and then go oops I can't drink because I'm pregnant 😜 But that's just one little mention at the very end and people might not even get it. 

UPDATE Whoa people here really hate this idea. The way I see it is a wedding is a family event. And what makes a family happier than a new baby? I know for my parents this will be the cherry on top of an already wonderful day. This will be the very first grandchild in the family. I'm not trying to ruin my sister's day at all. She still gets to be a bride and all. 

UPDATE 2 To all the people saying I'm jealous: Why would I be? I had a great wedding and I have the best husband in the world. Have not talked to my sister about this yet. I don't think she'd be as upset as many of you say. But of course I'll ask her first. I'm not trying to make this about myself. I'm super excited bouncing off the walls happy and I wanted to share that happiness with my family.

And to the person who wants to punch me in the face on here: wtf?!? 

UPDATE 3: Today I had lunch with my mom and my sister. I told them that I'm pregnant and asked my sister if i could announce it to the rest of the family next week at her wedding. My mom was so excited she cried. She knows how long we've been trying and this is her first grand baby. My sister got pretty upset and said she doesn't want me to announce it because she feels like people will be more excited about a baby than a wedding. She said she doesn't even feel super comfortable knowing about it now because of my mom's reaction and accused my mom of being more excited about me and the baby than her wedding. She didn't even say she was happy for me. I think this is pretty selfish of my sister. This is not a competition. 

I won't announce it during my speech but I will tell people (my family like my aunts and uncles and cousins, not the grooms family and friends).
