Need your help ladies!

So I have been taking pregnancy tests and getting blood work done everything is coming back negative. I’m starting to believe there is something wrong and wondering if you ladies had the same problem. So I have been cramping on my left side for about two weeks nothing horrible just mild and I’ve had horrible nausea, tender breasts, no period and crazy food cravings frequent urination like every hour on the dot with a full stream and no pain and this is what my stomach looks like. Remind you I weight 109 pounds! I do have a doctors appointment on Tuesday but I’m just wondering what this bolting is from. It’s hard but not rock hard! Please help or give me your input
