... September and have been having 10 day periods since I stopped the Nuvaring. This month I am supposed to start again on the 11th. I saw spotting on the 3rd which is uncommon for me. The 24th I put in the diaphragm in and I didn't know it went in backwards till I removed it the 25th. Could I be pregnant since I had a little pink and light brown spotting when I wiped on the 3rd without any more since that afternoon?
