Sex on period?

M Bc has been gone for a month at college and have alotta phone sex and FaceTime sex but he came back today for two days. I was planning on seeing him and we expect to have sex but today I wiped and saw some pink. Now idk what I should do or how he feels with me on my period. I'm slightly uncomfortable with the idea but I'll still do it. My period was supposed to come later but it's slightly early. Does that mean it's light and I'll actually get bloody in a while or my period starts now? I should add we can't use his showers Bc we will be doing it somewhere else and since it's light I don't want him to see it so advice? And stories??
