Embarrassed ๐Ÿ˜…๐Ÿ˜‚

So me and my boyfriend of a month were having sex last night and we did foreplay and everything like that which means he ate me out. Well after we had sex I went to the bathroom and I was spotting... I know what you might think, he tore something but no that's not what happened in pretty sure I was spotting. I just think it's gross for him because I basically started my period as we were having sex and he doesn't have period sex. So has anyone has a similar situation? Did your partner notice? Did you tell your partner?
