I was suppose to get my period on Valentine's day but here it is almost a week later and still no period. I took a hpt and it came back negative, but idk if I took it too soon or not. My periods are very regular and now I'm starting to get worried, I'm not having my usual pms symptoms or anything, the only thing that is going on, that I can tell, is how the inside of your vagina feels right before you get your period and I've been real dry down there when it comes to sex. Anyone have any suggestions before I call my dr?
