HI Soul,
This is my 9th pregnancy and I have four live children. I hear you Sister!!!!
I always say I feel like somethings gonna fall out. I know my pelvic floor is fine. I seem to get aches where I havaen't had them before and sore lower back. Indigestion is a real treat - tummy already. I can feel my fundus now - I think I am only 9 weeks and 4days but my obs believes I am 10 weeks. So, it is pretty early to feel the fundus though not unusual in multi gravidas! I think what you describe sounds within the realms of normal - just get it checked out next time you see your care provider.
