Hi,
My stomach feels a bit tender and my abs kept tensing for no reason this morning when I leaned over (had to tell them to relax!). If it's not my stomach, it's my ribs!
My ab muscles felt sore from about 4 to 6 weeks I think. It was one of my first symptoms.
Edit to add. Lol sorry didn't see this was an old thread and I already replied to your new one
