Only a doctor is going to be able to give you a solid answer here, friend. I don't put a lot of stock in online medical research and diagnosis. Bad cramping could be caused by a lot of things. And cramping is different for everyone, so bad may be your normal.
I go to a normal doctor to get prescribed T. If there are general practitioners in your area that you know will prescribe, my recommendation would be to go see one of them and explain the situation. It helps if they are versed in trans issues. My doctor understands my aversion to pelvic exams and sees no point in putting me through one as I don't have a family history that labels me as high risk, and I'm not sexually active with men. So if they understand your feelings and your lifestyle doesn't label you as at risk, I wouldn't worry about it.
You may need to get some blood tests done though to rule out a hormone imbalance. They do blood tests when starting T anyway, so maybe you can see if they'll be able to use the results to diagnose your problem and as your starting lab work for T.
