I need some insight. My cycles are about 25-28 days. I got a peak LH test in CD12 (12/14) and had EWCM on CD14 (12/16). We BD on CD11 (12/13) and CD 14 (12/16). I did not confirm O with BBT just by EWCM. On 14dpo I started pink spotting and it was on and off for 48 hours so until 16dpo. It was pink, some red and brown. It was thin mucusy too. Never had to wear a tampon or pad. It was when I went to go pee and wiped. I got a BFN today at 17dpo. From what I’ve read, implantation bleeding can happen at 14dpo (the day I was supposed to start). Am I out or should I wait to test? How long should I wait to test before HCG is in my urine? Any positive stories for BFP after 17dpo?
