Could my symptoms indicate H. pylori bacteria infection?

One should get medical help as soon as possible. Your symptoms indicate the possible complication of your case due to hemorrhoids, for example blood clot. As for me, I would advise turning to a gastroenterologist or proctologist immediately in order to receive the right diagnosis and treatment.

Pain and blood in your stool can be a serious thing. Trouble in passing stool plus sourness are also not exempt. For example, hemorrhoids could be the cause although there are other causes like infections or diseases of the intestine such as IBD. Seek medical attention promptly for appropriate care must be taken into account as far as this is concerned. 

I think you might have a stomach upset. When you take birth control pills with L Thyroxin, you might experience diarrhea. This could mean that the combo is affecting your gut. Keep yourself hydrated and consider taking the drugs at different times during the day. If it doesn’t stop, talk to a doctor so they can advise accordingly. 

Abdominal pain after eating may be caused by the swelling of your intestines, which is a common symptom of Crohn's disease. You may ask your doctor to let you try a different drug that might work better for your condition. The right medication that is most effective for you and is helping with your symptoms should be found out soon. Therefore, you should not forget to tell your doctor about the other treatment possibilities.

You are experiencing some stomach upset and feeling sluggish as well. If you have had a fever, cold, dry cough, or/and muscle aches for the last fortnight or more, this might indicate gastroenteritis (stomach flu) or other viral infections. Rest, take fluids only in plenty, and eat simple easily digestible meals. If the condition persists or becomes severe seek medical attention without delay.

It seems like you may have hyperthyroidism. This occurs when your thyroid is too active which results in rapid heartbeats and discomfort in the abdomen. Additionally, it can be difficult for you to gain weight. Treatment may involve taking medications or undergoing other therapies that can help regulate the levels of your thyroid hormones. Therefore, you need to see a doctor so that they can diagnose and treat it properly.

Do not underestimate how black stool points to possible internal bleeding of your digestive system, nor your symptoms of losing weight and having no appetite. This points to the start of a severe health issue that would be more likely benign than malignant. Besides, it's best to go through the colon and intestine diagnostics first as well as some other medical tests.
