Should i go to the doctor? When covid is over of course

I’ve had regular periods after getting off of birth control but the past few days I’ve had really bad stomach cramps. It’s mostly on the left side and when I lay down at night it’s in my back and hips too. It feels like I’m being stabbed or something is stretching. I’ve been bloated and have had an appetite ive never ever had before. Normally I skip breakfast have a small lunch and a small dinner. I’ve been like that for 3 years because I’m never really hungry I used to have a very low appetite and food would make me sick. Now my appetite is HUGE and when I eat I have to take tums because I have bad indigestion. Normally I can always poop when I need to but lately the past two weeks I’m super constipated! I still have bowel movements so there’s no blockage it just takes longer and harder for me to go. And I’m super gassy when i never really been before. I don’t know what’s wrong with me! Edit : also super super thirsty
