So my period just ended about 3 days ago and it was 21 days long and I haven’t had any bleeding for three days the day before I got off my period and the day after me and my boyfriend had sex and and finished in me both times. I know implantation bleeding happens about 7-12 days after you’ve had sex so I don’t think it’s that but tonight I went to the bathroom and when I wiped it was like watery light pink blood. Is this just some sort of after period blood or something? If any one knows please let me know! Thank you !
