Would make a sense with my belly Button so sore
There's a chance it may be a hernia. Like the above said, your doctor's advice would be best. Good luck, I hope you find some relief.
I'm going next week but its in my groin
The list of things that hurt alot when sitting on a toilet include (but are not limited to) are thrombosed external hemorrhoid or a perianal abscess. You may get some temporary relief with a sitz bath or a small amount of warm water in a bathtub. It does however really need to be seen and examined by a physician.
I recommend getting your obstetricians advice on this one!
