M.C.
After my tubal I would have random pains in my lower abdomen. Sort of like phantom ovary pains. I have since learned that these pains are part of my body still trying to go through a normal cycle.
Painful cycles can also be a sign of endometriosis. I had this also. Mine was discovered through an ultrasound.
A friend had something similar and for her has learned that she had a thyroid issue. For that she changed her diet to lessen the gluten and her thyroid issue and abdominal pains have improved.
