Self Esteem and Confidence

I have never really had a good self esteem or any confidence in myself, whether it be physical or otherwise. I've always been on a journey to accept myself and gain confidence but it is still so low. What are things that helped you gain confidence and self esteem? I know that losing weight and getting in shape will help me a lot personally, but that's on pause since I'm almost 29 weeks pregnant lmao. I am going to do some exercises, but no losing weight just yet.
