Hey, firstly please calm down. I can understand the amount of stress you might be going through at this point and how excruciating the pain can be. Good times will come, just have faith and keep breathing till then.
For my own IBS, lifestyle changes helped a lot, and cutting down a lot of food items that didn’t suit my gut helped a lot. I suggest you try doing the same with the help of a nutritionist.
I am not the best person to go to about the reproductive issues part. So, I will stick to the gut problems for this answer.
6th house represents our intestines and the actual digestion process. It also signifies our daily routine and actions in general, apart from signifying enemies, sickness and debts. I suggest volunteering or donating at a hospital or sixth house related places. You need to cleanse your sixth house, that means cleaning up your entire lifestyle. Try reflecting on what you do, and make holistic changes accordingly and gradually. Try going to temple daily and donate something everyday.

To put in an astrological perspective, the gut bacteria are there in order to keep our digestive process functioning. And when our gut is sick, it means that the creatures living there are dying. The environment is becoming inhospitable. The jeeva or jupiter is moving away. And then the problem rolls over to the 7th house, i.e, your reproductive system. It’s a snowball effect. You need to feel alive from inside, gut is our second brain. So when you feel any negativity, it affects the gut easily. Please try reiki healing, see if it helps. Work on your own energy cleansing and lifestyle changes with the help of professionals. And definitely seek medical help.
I hope everything gets better in your life very soon. My best wishes.
