i dont think i ever actually had pain, as in sharp or cramping...however, i as dry more often than not, and was crazy mean 9 days out of 10...and i only actually used it for about 2 weeks or maybe 4, but i couldnt handle it, and as crazy as it sounds, it just wasnt worth the bs it caused me...fiance was scraping it with his penis, and would get a really red dry patch, but if i took it out, then we were both fine...however....i do not think it will make much of a difference by putting it in a day late...my obgyn said it took effect alot faster than oral controceptives did, b/c like the depo shot, it didnt have to travel anywhere, and it went directly where it needed to go...
Sorry about your pain! I do not like NR at all! After the birth of my son I was prescribed NR. At first I really liked it. But after a few days I started having horrible pelvic pain. I remained on it for several months before the pain was so bad I couldn't do it anymore. But it's been nearly a year and the pain is still there. Though it's not as bad as when I was on the BC. Something in the back of my mind makes me think it is related to the NR.
You should monitor your situation very carefully. That burning sensation isn't normal and a doctor needs to determine the cause. It may not even be related to the NR. But like I said before, I have a bad feeling about it. Good Luck!!! I hope you feel better soon!
