what the heck is this 😖

Angel • Mother To A Beautiful Baby Girl ❣️👩‍👧 .
 Early this morning I noticed this on my stomach , I originally started noticing maybe 2 weeks ago that the bottom of my stomach just felt really weird , lopsided, gushy & nowhere near hard . But just last night/ early morning this was the worst I've seen it . My boyfriend's mom says she's thinks fluid is leaking inside of my stomach and when she said that being that this Is my first pregnancy you can bet I got scared as crap  & im currently 9 months . I don't go to the doctor until Thursday , but should I go to a hospital? What could this be ?
