So, I've been testing for about a week, and I'm 13 dpo. All BFNs* (a few had super squinty shadows, but I couldn't see any color in them, and it could have been my imagination or just the fact that I was using iproven tests from Amazon). AF was due today but no sign of her yet. Is it too late to hope for my BFP or is there still a decent chance? I had a headache and light bleeding/cramping at 7-8 dpo, and I have super sore nipples, but I'm missing the munchies that always show up right before/during AF. DH and I are trying for our first - have been since August. I have PCOS, but I started Vitex 1.5-2 months ago and I'm fairly positive I ovulated this month. Only started temping a week ago, but they've been fairly stable....no sign of an AF dip yet.
