My period has vasillated for years. It can be meds or Lupus attacking feminine system. I had a year where I had 4 operations in feminine areas and my cycle was all over the place. Also don't forget that Lupus and hormones are closely related so it will or can alter cycle in some.

Happened to me once.

I stopped having my period for 4 years! Then it just started again. In the time I didn't have it, my weight went up, then WAY DOWN, my meds were changing often. When I stabilized, after approx a year it came back. Hope that helps
Also, pregnancy tests WHEN TAKEN PROPERLY, especially taken after the proper time period, are pretty effective, but if u need definitive, a blood test is the best way to go

Kristen, prednisone is a horrible medication with many, many side effects. When I was first diagnosed with chrones disease I was on prednisone for 2 years straight and another 6 months to get off of it. I had all kinds of side effects and that was one of them and to date I still am not having normal periods. Along with weigh gain, moodiness, restlessness, swollen ankles, feet, and hands. It may be a "miracle medicine" to some but I will never go back on the medicine unless I have no other options.

Wow I want to have kids soon so I hope it doesn't fully stop! Thanks for the info.
