We have been TTC since December 2016 and that is when I had my last withdraw period. I had a very light cycle in January (a few days before the cycle should have started).  This spotting lasted 5-6 days. I didn't think it was a period but I still tracked it in Glow. For the fun, I took ovulation tests in February and after 3 high peak days, I received the solid smiley on February 8. I felt different this month, more cramping than usual, headaches and fatigue. I didn't think anything about it until yesterday when I had light brown/pink discharge. It was just that one time and it has gone away. My question is, could that have been implantation bleeding? Can I still ovulate if I haven't had a heavy period? I'm thinking of taking a HPT tomorrow morning, which would make me at 13dpo. Do you think I'm still not regulated after stopping BC and the ovulation test was a false positive? This is just so confusing!
