Here we go again... TWW#2

It's 1 DPI, or two, depending on whether I count from the first one or the second. In any case, inseminations were done yesterday and the day before after a +OPK on Tuesday afternoon. My BBT hasn't spiked yet, though, and the OPK was two days later than expected, so I don't know what's going on with my body this cycle. I guess we'll know in a couple of weeks.

What's different this time?
1. I bought a digital OPK. It's a lot less subjective; there's either a smiley face or a big fat zero. No more comparing two lines, trying to tell if one's as dark as or darker than the other. Maybe I mistimed the IUIs in round #1. Maybe I only imagined that the line was dark.
2. Inseminations on CD16 & CD17, a full two days later than last cycle. The OPK turned positive at 4 in the afternoon (I took to testing twice each day, CD13 until positive) on CD15- too late to schedule an insem for the same day. It was negative at 5 that morning.
3. One IUI on CD16, then an ICI on CD17. The midwife who did the IUI suggested that there would be more viable swimmers if they were just thawed instead of thawed AND washed. It seems counterintuitive to do that on the later insem, but she's the one with experience so I decided to give it a try.
4. Pineapple juice. Every day. I read in multiple places online that pineapple promotes thickening of the lining of the uterus, increasing the chances for implantation. So I bought a case of small cans and have been downing 1 or two daily. If nothing else, I'm getting plenty of iron and vitaims A, C, and E.
5. I took three days off from work this week to make sure I was relaxed and well-rested for the insems. Of course, my timing was off, so I had to split almost as soon as I returned to work on Thursday morning ("Hi- now that I'm back, I just need to leave in about 45 minutes. I'll be back by 3!"). I also did it to avoid having to explain my midday absences to anyone.

I'll know in about 10 days whether or not these changes had an impact. I hope so. We'd be due in June... Father's Day, perhaps?
