I’ve been having abdominal pain, lower back pain, diarrhea, heartburn (sometimes), if I so much as feel a little bit hungry, I feel like I gotta throw up , after I eat I have to throw up. I just ate earlier & my stomach got bloated & I’ve been very tired lately & drink a lot of water . I haven’t start my cycle this month but I already took two pregnancy test and both were negative. My cycles are always off . Either anywhere between the 12th-18th I usually start and I didn’t this month but sometimes I can miss 2 or 3 months and then start the 3rd or 4th month. All I drink is water so I don’t understand why I would have a bladder infection if that’s maybe what this could be. I have no idea. I really need advice.
