HI S.;
I too used to be on Depo. At first, you think this is great;no periods. But that is not good; I don't care what anybody says.
It's natural and good for a woman to have periods. I decided to give it up. Not because it made me gain weight but because a friend who is a holistic practitioner, said that the above as well.
I did notice after I stopped, that I had aches and pains that were unbearable. I got tested for everything but nothing came up. I saw many doctors again, nobody found anything wrong. Thank goodness.
I would definitely call your OB. I know I called my OB when I was having issues. He said my period issues were due to breastfeeding. I know that you can miss a period while breastfeeding but having a short cycle really scared me.
He put me at ease. Also, I loved the fact that he said, "don't do this to yourself." I thought there was something really wrong with me. Even though, I am breastfeeding, I still get my period.
Put yourself at ease and call your doctor today!
Best to you.
