Menstrual cramps or what?

I be wondering if anyone would know why I would hold cramps close to I am have a menstrual cycle but nought is here. Its almost a phantom cycle or something. But because of when I experience these cramps I hold usually already have my cycle. Sometimes I hold skipped a cycle, but I would experience menstrual during the time I am suppose to hold a cycle. I enjoy have a transvaginal sonogram and he said everything looked right, my pap smear come support fine as powerfully. I move about to the Dr. on the 8th of subsequent month for blood test. Has anyone experienced anything similar to this since? Am I experiencing fruitless PMS, as a rule I enjoy not be experiencing PMS until going on for I week previously my cycle. But this awareness come and go through out the month and when I am have PMS I will hold on to experiencing discomfort until I finally own my cycle. What is up beside this? Another point is I am not currently taking any Birth control pills and I enjoy not be for roughly 2 years.

why does it itch?

Things approaching cysts and within some cases endometriosis can motive the features of affliction you are have. In relation to cysts sometimes they don't other show up on ultrasound (I've have it come about to me).

I would recommend consulting a gynecologist if you haven't already to see what they vote.

If you own and the results still show majority I would recommend getting another feelings and preferably from someone that does not share duplicate organization of the doctor that you currently see.
