Sorry for the TMI post. I have a 41 day cycle and I'm currently TTC. Ive been trying for over a month now. I'm currently 3DPO and my period isn't due for another 2 weeks. Today I got cramps and all of a spotting (very light pink not enough to fill bad or tampon and only when I wipe) past week ive been so moody and a little bit nauseous. I tested the morning and got a BFN, could this be implantation (had sex within the last 12 days)? Or an early period? The negative test has really thrown me off. Thanks x
