So on the 3rd of December I started ovulation but it's the 11th now and I'm having very light spotting with dark and pinkish color and i only see it when I whip but me and my bf had sex on the 8th my actual ovulation day but we used a condom.. but before that I believe we had sex on the 30th of November and he came inside me but I started birth control on 22nd on Sunday 2 days after my period started so what's happening? I don't understand and need some help please
