Thank you all for your kind words and gifs yesterday! I'm feeling much better today.
I got fuuuuucked up on painkillers last night, woke up this morning feeling a little crampy, but I'm almost back to normal right now. Just feels like moderate period cramps, and they are intermittent. I took a 3 hour nap today, so I feel great. I also haven't taken any painkillers at all today, so I'm thinking the worst of it is over.
I'm so happy with my decision! Even if that terrible pain had lasted all freaking weekend, I still think it would be worth it. I'm excited that I won't have to worry about taking a BC pill every day (after the next week, the doctor said to stay on it right now until the Mirena becomes effective). It feels weird knowing that there's a little plastic foreign object thingy just stuck up there for the next five years, but I'm sure I'll eventually forget about it. :)
This whole thing also made me see MitsuBT in a totally different light. He took an entire day off work to take me to/from the appointment, and then spent the entire day/night taking care of me. I was whiny and sullen, and he handled it like a champ and never complained or got cranky with me. I spent most of the day curled up in the fetal position and whimpering, and he gave me back rubs and pretty much waited on me hand and foot. I have never been with someone who took care of me like that; my own mother was never even that nurturing. Tonight he's cooking me dinner at his place, and we're gonna drink wine and chill in the hot tub. He's such a great guy, and I'm extremely lucky to have him.
I hope everyone else is having a great weekend! Thanks again for all your support, GT. I got the warm fuzzies reading all your comments. I'm sorry I didn't feel well enough yesterday to respond individually.
