@megan413, I had a gender reveal party at 20 weeks right after we found out what we were having. (even tho we did even know what we were having til the reveal party)and now I'm having my baby shower next weekend and I will be 34 weeks.

I did my gender reveal and shower at the same time. I was only 25 weeks when I had my shower but I also had my son at 33 weeks so early was better

I don't think you get presents at a gender reveal.... so I would say it's safe to have both! :)
