So happy !! ? question tmi

Brittany • Christian Mother , & wife ,baby number two Due march 27th??
We got our first bfp today we are expecting number two march 27th! My symptoms are so different then they were with out first .. I have had horrible diareaha for almost a week and a half now ? I'm assuming this is normal ? With my first I was constipated the entire time .. Any insight to make me feel better will help ! I'm terrified about everything
