Hello Rachel, Thank you for posting to us. Per your description you are having problems which might be unrelated. Your stomach pain and bloating is due to indigestion/dyspepsia. We could also think of an irritable bowel syndrome. In that case, you will need antispasmodic medication and sodium bicarbonate salt dissolved in a glass of water. Non the less since we are dealing the stomach, it is better to run some few test like stool exams, urine analysis ( to exclude urinary tract infection which could mic mic abdominal pain/ nephritic colic). Your postcoital bleeding might be due to an affection of the cervix (infection, abnormal cervical cells, tear etc). You will need a PAP smear and vaginal exams by a gynobs to exclude this. The other possibility of your bleeding is from the lining of your uterus in case your uterus is easily destabilized. Some women can have this bleeding during ovulation or right before her menstrual flow. Infections such as gonorrhea and chlamydia can also affect the lining of the uterus and cause weakness thus bleeding after sex. Uterine abnormalities such as polyps or fibroids could cause weakness and thus bleeding after sex. In any case, you will need to pay a visit to your gynobs or you can allow to see if any recurrence or related to ovulation or before menses ( you may wait before going to gynobs). This might not necessarily be an emergency. But if worried do check up. Hope this helps
