Normal AF, but maybe pregnant??

Could this be possible? I'm still breastfeeding, so I have been having anovulatory cycles since I started AF back when ds was 6 months. I've been temping pretty religiously and was checking my cervix, also. This past month, though, I got really slack. I did not check my cervix at all and I went on a trip to Stockholm and did not temp the whole weekend I was there.

My temps have been really low (which I attribute to the BF and frequent night wakings since I co-sleep with ds). The night I got back from Stockholm, dh and I GIO . Since I had been anovulatory, I just said screw it and didn't care if he finished inside of me. Well, the next day I temped and was up to 97.4! The day after I went up to 98.5 and then thereafter I was in the upper 97's. My temps have been in the mid to upper 96's normally. At 8 days after possible ovulation, AF came to visit so I thought that was that. But my temps have still been up! Its two days after AF is done and my temp has been 98.6 two days in a row. During AF my temp never dropped below 97.4 which is still high for me. AF was normal - light to heavy to medium to light to spotting.

So, what do you all think? Could I actually be pregnant? Has this happened to anyone else?

TIA!
