<human>: Can you condense the text into three sentences or less?

My FSIL is pregnant and is due 3 weeks after our wedding date, yay babies! We are very excited for her and her husband, this is also the first grand baby for my future in-laws (so as you can imagine everyone is very excited.) When we got engaged in October FSIL basically volunteered to make cupcakes for our wedding, which is very appreciated and sweet! (She made them for her own wedding as well and they turned out great.) We also asked her to be a part of the bridal party, because honestly IDGAF about bridal parties and traditions but it was important to FMIL. 
Well, now that we know she will be super pregnant at our wedding, if not already given birth??!! I feel like I should let her know that it's 100% ok with me if she doesn't want to be in the wedding party. I'm worried that she will feel obligated and won't say anything. I'm prepared to at least let her know we are doing cupcakes through our caterer to make the day of easier on everybody. 

I should also add that FH and I both do not live close to our families and both sides will be traveling from out of state to attend. FSIL and her husband are planning on driving for the wedding, which is about a 7 hour drive for them. 

Ugh! I don't know what to do....FSIL and I are not close, I've been around her maybe 3 times in the 3 years FH and I have been together. So I don't feel like we can just have a heart to heart about this. We have pretty much nothing in common and our personalities are not at all alike. I want to be on good terms with her now and in the future, but I just don't know how to make that happen!
<bot>: Not close with FSIL who could be mega-prego during wedding or have a brand new baby. How do I tell her she can skip out on being a part of the wedding party?
