Rafting 6w6d?!

Well I had planned rafting with my ladies before one get married and now I found I am pregnant. Would u all still go? This is baby #3 for me and I went snowboarding for the first time with baby #2 at 6-8 weeks and sick. I surfed from day one all the way till 7-8 mowith baby #1, I just wonder if it would be similar lots of cushion now for baby so probably it so bad? I also don’t want to tell these ladies just yet why I can not and I am a really bad at lying.
