My cycle ended on the 12th it's been three days since it's ended. I have had sex since then as well. I went to the bathroom and when I wiped I saw pink looked like a little blood in the toilet. Next time I went to the restroom and wiped I saw a little pink again nothing in the toilet that time. I'm confused.
