pregnant and sledding

Prevost • 29♋💏Happily married💕Baby boy 11.8.18💙💚 TTC#2

I just found out I'm pregnant and my husband doesn't know yet. He has planned a couples sled trip to the mountains for this coming weekend. Hoping he will change his mind when I tell him on Tuesday but if he doesn't how bad would it be a bad idea to go?
