so i jus started the nuvaring almost 3 weeks ago after my period was 12 days late as my Dr requested. But about 3-4 days before I was suppose to take it out I was spotting like bright red. Then 3 days before I was suppose to take it out I was having super bad cramps and started bleeding bright Red n really heavy so I took it out. I woke up this morning, I was still bleeding extremely heavily and I passed a like black chunk that was about the size of my palm and thick. Is this normal?
