FIRST TIME MOM!

I’m 25 weeks and 3 days pregnant now and for about a month or 2 I get this very sharp persistent, upper back and stomach pain sometimes it’s manageable and sometimes it feels as if I need to go to the hospital, it’s happened a total of 4 times now each time progressively worse and longer and it only happens to me in the middle of the night (wakes me up)

Has anyone had this? If so did you figure out what it was?

Will be asking my midwife when I see her.
