Missed AF /nuva ring

Briky <3 • Turning 30 this year 🙈 trying for our 3rd 💚

Sorry if this is a little long. But I was hoping to get some thoguhts/personal experiences about what is going on.

So I have been on nuva ring for almost 2 years now. I've always been really regular on it. I'll have AF for 2-4 days and it's generally light but I definitely have it for 2-4 days. When I went and saw my doctor in February I told him how I was getting married in April and I was supposed to have AF on my honeymoon. He told me that I could take it out and put one right in and skip a period but not to do it often. I did that and then AF came very heavy and for 5-6 days at the end of may. Since then I haven't had a period. I took one pregnancy test after my second month of missed period and it was negative. I called my doctor last month and explained the situation to the nurse and she said to just keep using it sometimes on birth control you won't have AF come. But it's really stressing me out not having a period. I've missed 2-3 more periods since I took the pregnancy test but I don't feel any different (like I'm pregnant though I've never been pregnant before so who knows) But is there anything anyone suggests? Have you had your period missing for months on nuva ring or other birth control. Is there anything I could do to maybe get it to come back without going off of it? I have enough going on I just want to stop stressing about not seeing AF in so long.

I really appreciate any input! Sorry If I rambled a bit! Thanks!
