Had unprotected sex with my partner on the 4th day of my cycle. (2nd time having sex with him in general) I still was bleeding from my period. I usually bleed for 3-4 days. He pulled out before he released. Afterward, I bled, period blood, I think. It was red and had a few clumps, like my usual period. Should I still take the 8-pill levornogestrel solution?
