Got a possible big update. Okay. So the past few bbt's since Tuesday are: 97.7, 97.7, 98.1, 97.7. Today I am 8 DPO and counting. A few minutes ago when I went to the bathroom, I noticed some very light pink spotting on the toilet paper. There wasn't that much of it ... just a tiny bit. (TMI, I know. But I'm hoping that this is it!) I normally don't spot after ovulation, and even if I start a few days early it's usually around 11 or 12 DPO. I'm not supposed to start until April 2nd. I've also noticed that my CM has come back with a vengeance. I took a test yesterday and one this morning but they came back negative. Probably too early. If what I'm experiencing is implantation bleeding, then when can I take a test? When does implantation bleeding take place? I didn't have it with my first pregnancy. I'm getting super nervous/excited.
