lower abdomen always sticks out

I’ve been dealing with this for years and I want to find out what the cause of this is finally. For reference i’m 26F 5’7 130 lbs. I have always been naturally very slim but my lower abdomen always sticks out.. a lot. I also am always very bloated and I have been trying to tackle that issue too. I don’t know if this is just fat or something deeper, i’m leaning towards the latter. I’ve seen so many reasons for why one’s stomach could do this and now i’m overwhelmed and don’t know who I should consult with first. Any tips anyone?? These are pics of how it looks in the morning and before I go to bed.
