I'm worried sick ugh?

It might be just nutritional deficiencies. Certain nutritional deficiencies can cause indigestion, bloating, missed periods, etc.. Seriously, google to see for yourself! If you don't have enough vitamin B12, vitamin B1, and zinc (and probiotics!) you can get indigestion and bloating. If you don't have enough iron and vitamin B12 you can get missed periods. you can get your nutrient levels checked out by the doctor/nurse. they will take a blood test to see if you're low in any of them.
