Why can't this just be simple!

At some point this month I am due for my period.. Im never on time so I cant say when.
I've been feeling pretty good since my surgery settled down. I have been exercising and all that jazz. I've felt 'ok' for the first little while in a long time it seems.
However Saturday night I was awoken by cramps that had me in tears and near screaming. I was bent over in the foetal position but laying on my legs praying it would stop soon. I was this way for a good hour or so then it subsided. I was exhausted Sunday just resting..and I get getting bouts of these cramps and currently still are. I'm so terrified I'm going back to where I was. I know I 'should' be due for my period realistically by the end of the week. I feel so helpless, I keep trying with failure. But I am biting the bullet, Not whinging hoping it's just a passing phase.
I will not hesitate to go back to the new gyno if I continue to get worse. I may be 'endo' free - but besides natural suppliments and 0 hormones I have nothing stopping it from returning with avengence. It's obvious it does return quite quickly...evident from surgery 1 to 2.
Im also battling a UTI.. drinking and taking medication.
Please god, give us a break sometime soon? All us women with this disease need one!
