Hello,
Hardness or discomfort of the abdomen is commonly due to
acid reflux, IBS,
gastritis, etc. You can take antacids and PPI's for relieve. Stay well hydrated & take laxatives at bed time. Take adequate sleep. Heavy
bleeding after intercourse is commonly due to rough sex, infections (PCOS), tears or ovulation.
Other medical conditions causing it may be fibroid, cysts, polyps,
implantation bleeding, etc. If you were not on regular BC pills and forgot to take the emergency CP, you may be pregnant. You are suggested to get clinically examined by a GP. Get urine and blood tests done to rule out
pregnancy. Get imaging (USG of uterus) tests done to detect the pathology. Your treatment will depend on the pathology detected and your clinical condition.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
