So, update:
I guess everything really is different for everyone because that hurt like hell!!!! I had to breathe like I was in labor and brace myself against the wall because the urge to writhe in pain was so strong. I was really surprised it was that bad 😕 At least it's over!
Thanks, you guys, for the reassurance. It helped!

It's fine. Just a sharp cramp at first and some minor cramping later on. Take an Aleve or Ibuprofen before you go. The first 6 months can be cray cray. Periods out of whack, cramping here and there, moodiness. But that's birth control, its hormones, so no one gets preggers. I've had it for almost 2 years and I don't even have periods anymore. I have what I call invisible periods, lol. I still get PMS and bloating occasionally. But the plus is that I haven't gotten pregnant.

It’s actually relatively simple. Just like a Pap smear like @lillynellasmom said. Takes a few minutes. (I’m blanking on what the tool is called) they open you up, like for a Pap smear, place it, trim the strings, voila! You leave 😅 you’ll do good! New things are always scary so I understand 💪🏻

I had it done twice now, its not a big deal its done so fast and you dont even feel its there. Just little bit crampy after but it goes away.

I wouldn't say it's that invasive I mean it's kind of like in a pap smear and they put it in and then they're done I don't think it took less than 5 minutes when I got mine done/put in really didn't even feel it.
