Keen to get people's thoughts or experiences on this:

I'm on day 27 of a 29 day cycle. Since day 25 I've had the lightest 'bleed' ever (spots of red, pink and brown) but my usual period follows a classic pattern of light red bleeding on day 1, followed by two heavy days then two lighter days. This is nothing like that. I've POAS day 25, 26 and then this morning: all three were negative.

My temp today (not bbt, just taken after breakfast) is 37. I'm normally around 35.6.

Other than that I feel no different. I've never had implantation bleeding before so I wouldn't know what to expect. Thoughts anyone? Could I be pregnant with a bfn two days before af is due?
