The tiniest streak of blood

Hi all! TMI pic. My periods have always been irregular, and sometimes I’ll skip a month. It’s now September and I haven’t had a period since around May or June. I’m not on birth control, and me and my husband have been using the pull out method for 2 years (even though we know there’s a risk with that). Well anyway, the past few days he has finished inside of me as we are TTC for #2. I know it would be way too early for implantation bleeding, but here lately when I go to the bathroom I’ve noticed very light brown (almost beige) discharge, and sometimes it’ll be pink discharge with a tiny streak of red blood. My periods are usually very heavy so this is out of the norm for me. Any one else experienced this? Xo
