Very itchy lower stomach 😤

Hi guys, I have been experiencing a very itchy lower stomach. It gets to the point where I'm itching so hard that it's like breaking open my skin and causing little tiny scabs. Is this a sign of my stomach stretching? I need good recommendations for some creams or ointments to try to help this because it is very annoying! My doctors and nurses have seen my lower stomach when they check for heartbeat or do ultrasounds and never say anything so I'm assuming it is normal.
