So I was supposed to start af either on March 12 (my birthday yay!) Or March 13 but I've had nothing but minimal brown spotting the past two days and today. Sometimes when I wipe, there may be some red/pink/ewcm but that's it. I've never had a cycle like this before. And on March 12, I had a glob (sorry) of ewcm come out and when I wiped which is unusal for me right before af. FF says I ovulated on the 3rd of March, and we bd that day. Glow and a few other apps say I ovulated on the 27th of February and we bd at like 1-2 am that morning. Is it possible I ovulated late making me 12 dpo today and I'm having implantation spotting or you think af is creeping up on me? (I didn't temp this cycle and my ovulation tests came late in the mail and all tests have been bfn so far.)
