Just this week had a miscarriage at 6 weeks. Tried to change that on glow that I was no longer pregnant but only way I could was to change to trying to avoid pregnany, witch is like sort of what I want to do now at least till 3 months after I'm married and moved back into our own place and out the in laws and won't heve all this stress on me. But can I delete all my past periods and just start it all again once my periods have returned? Or will it not make a diffence on my cycle if i still have all my past periods logged in? Any one know?
