Hi, welcome to our site. I am Dr Saumya Mittal. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query i dont think this is related to the intercourse. so i dont think you should worry about that to a certain extent, the pain can be explained by the ovulation. but i am guessing that this has never happened before (else the query would be on earlier) what you have developed is probably something like irritable bowel syndrome. however the duration is too short to say so. but yet your symptoms fit into that syndrome i would suggest you start some antacids like omeprazole, take some stool bulking agents like isapghulla, and try antibiotics liek rifaximine. of course this latter will be on for a longer time if this does not help, an ultrasound, stool routine and endoscopic examination may be planned I hope this helps you. Inform the reports mentioned above so i can be of help further. Best of luck. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this)
