Firstly, I didn't get my second period as expected. I sort of freaked out, since I'm so used to it being exactly on time during my four years on the NuvaRing. I got the cramps that should have signaled it starting, but no blood at all. So, I waited a week. It still didn't come. I took a pregnancy test and it was definitively negative, which was good. I decided to just sort of wait it out for a while longer because I read some stuff online about how the IUD (even the copper one) can screw with you for the first few months.
I kept taking pregnancy tests, still negative, but still no period. Finally, after the period that was supposed to come after my already-missed period was late, I called my doctor. She had me come in for a check-up. The IUD was still in place and everything was fine there. She sent me for some blood work just to make sure things were okay. She said her best guess was that my body wasn't used to ovulating yet after being on hormonal BC for so long. So, although I still had enough lining stored up in my uterus for the first period, I might not have another period until my body decided to ovulate again.
A couple of days after the check-up, I got my period. Go figure! It was moderately crampy, but not very heavy. It lasted about 6 days and then appeared to go away. For a couple of days after, I was fine, and then I started bleeding again. Not quite heavy enough to be a period, but not quite light enough to be spotting. Very annoying. That's still going on and it's been about 10 days. Sometimes it's super light, sometimes it's heavier. I'm trying to take Advil to see if that helps.
Also, I got the test results in the mail from my doctor. No pregnancy - yay! But she did note that I have a "mild case" of polycystic ovarian syndrome. She noted on the letter that I will probably never have regular periods, and asked me to call her to discuss. I called today, but she hasn't gotten back to me yet.
Overall, things are slowly still getting better with the cramping. I still have random cramping here and there, but it's less and less each month. I'm still happy with the IUD.
