So my wife is on a 35 day (average 32~35) cycle. Ovulation was predicted on CD 16 w/temp increase and Peak fertility on Ov. Kit and today would be 10DPO. Last night she had slight tingly cramps and super light pink spotting with consistency of egg yolk. On 8DPO she had fatigue and an odd headache. We are TTC and trying not to read into anything or get excited. Is any of that a good sign?
