Nuvaring

So the 6th and 7th of December I had unprotected sex and took a plan b . And on the 9th decided to put my nuvaring in and “skip” my period which was supposed to be the 14th of December. I’m scheduled to take it out the 29 -30th but would my AF be super heavy and painful since I skipped a month . This is the first time I’ve done this and I’m not good with pain .
