NEXPLANON

Y’all. I had nexplanon for like 10 months and got it out in June. I had my first period July 22nd. My period is 16 days late and every single one of my hpt’s came back negative. I’m not super stressed and when I had nexplanon 2 years ago and got it out my periods didn’t skip like this. I’m always regular with 5 days bleeding and never more than a couple days “late”. Has anybody gone through this with nexplanon after removal?! I’m not ok any other birth control!
