M.H.
I am having some signs just like that right now and I also have not had a menstral cycle since Oct.20 so I thought I was pregnant I had taken 4 negative pregnancy tests and decided since it was already into Dec I better do something so I went to the Dr Monday and he set me up to do an ultrasound to see what it is cause with my symptoms he said it could be anything from a tubal pregnancy to endomitriosis to a cyst to some form of cervical or ovarion cancer.. I go to do my ultrasound today and I will try to get in touch with you and let you know what they find maybe it will give you some idea of what to do hope this helps..
