Cycle Update - Implantation Dip?

So, for a quick recap:
I got a positive OPK on the day after my Wordless Wednesday post last week, meaning I ovulated on Friday. I had a temperature dip to confirm that so I knew. The problem with that is that it was before my normal predicted fertile window, and it was 2 days before I expected to ovulate. So, we didn't get as much BDing or time it very well (couldn't DB every other day like planned). In one way, it's probably a blessing that it happened early because it was supposed to happen the day of the Superbowl and I'm sure not much action would have been had since we were hosting a party.

Today I am at 6DPO, and I had this

Implantation dip maybe? I am going to keep temping normally until it goes back up (hopefully shoots up tomorrow or it's not an ID). For sanity sake, after then, I am going to chart in the evening instead of in the morning. That way, low temp won't ruin my day.

FX!

Obsession

Ah yes, I have been obsessing. I'm in my 2WW, little more than half way through, and I've just about worn out the chart overlay button on http://www.fertilityfriend.com

Yesterday I had a dip of a half a degree and this morning it was right back up, classic signs of an implantation dip. I also had some minor achy and crampy feelings last night while we were at the football game. They were bad enough that I wish I had brought some Tylenol and that I wasn't standing most of the game.

The only thing that does concern me about today's temp was that I didn't go to bed until about 2am and we realized that the house temp was set much higher than normal (almost 10 degrees since we drop it down when we sleep), then the cat woke us up at 4:30 and I was so hot that I had a hard time getting back to sleep. So I had 4 hours of interrupted sleep before I took my temperature. I'm not sure if that would give me a higher or lower than usual reading. It is noted on my chart but it is driving me crazy! I want to go to bed and wake up in the morning so I can get a more accurate reading. The only down side to that, is well tomorrow is Monday. :(

As for signs and symptoms, I have reverted back to how I was before I started TTC and charting. I rarely ever had any PMS/Pregnancy symptoms. I was always tired during the 2WW, but never realized it was related to the progesterone. I never had sore breasts or mood swings or bloating or anything like that. Usually exactly 7 days before AF I would have a bout of irritability, then sometimes I would feel down or be more sensitive. So my chart has been pretty bare, and I'm currently at 7DBAF (Days Before AF) and no signs of irritability or sadness. The only thing that's been a little unusual is the cramping I've been feeling. Whenever I get cramps, it's usually w/i hours of AF arriving.

So FX and *babydust* for me for a BFP. If temperatures are still high tomorrow, then I'll probably test before DH's SA this week, but even then it might be too soon for a positive.
