Planning kids around events?

So my husband and I have been talking about starting to ttc in September or October.

We just found out we are invited to a wedding next September. (One of my husbands good friends and he is really excited about it)

If we started to ttc this September and got pregnant right away, we would potentially have a 3 months old at the time of the wedding.

So I guess my question is for the moms...

Would you rather be very very pregnant (7-9 months) and go to a wedding?

Or have a teething 3 month old who is still breast feeding and go to a wedding?

I know there are so many variables. But we really want to start a family soon and be as normal as we can!

I don’t mind pushing back ttc a few months, but I wasn’t sure what would be harder. Being near the end of your pregnancy or having a very young infant?
