There was another thread about this, where it was mentioned..

I have been on Depo for 3 years and have not had my period until a couple months ago..(started Atkins maybe 4 months ago??) So Im blaming the spotting on the new WOL.. I spot like, every day, and its not heavy by any means, but.. its just kinda nasty that its even happening..

When I go to my new gyno at the end of the month Im going to find out about some other methods of birth control..(not pills or patches..) but more along the lines of MAYBE a new IUD thats been out for a couple years in the US and out for a lot longer in Europe called Mirena.. it slows down, lightens your period supposedly because it has some hormones in it, plus its an IUD.. better than the old Paragard (copper) IUD..
