On 12/9 I took out my Nuvaring. On 12/12 my period started. On 12/16 I inserted another Nuvaring. On 12/17 my period was supposed to end. However on 12/19 I was bleeding again and I’ve been bleeding off and on (mostly on) since. Sometimes I’m spotting, other times I feel like I’m still on my period. I’ve tried to take ibuprofen to stop it and it’s not working. Why is this happening and is there anything I can do to make the bleeding stop?
