I woke up this morning and one of my nipples had a thin white-ish fluid coming out. My breasts have been very sore the last couple of weeks. I'm not sure what's up with that... I've gained weight in the last couple of weeks. My period should be showing up this week sometime... I don't think that I'm pregnant... I've spent a couple hours looking up all sorts of possibilities... basically I've gained weight, I've been hungry all the time, my right breast is leaking and both are very sore, I have no sex drive, I'm tired all the time... all this has been happening over the last couple of weeks. As I said I'm not expecting my period until later this week sometime... I realize that most of these things would point to pregnancy but I thought that the leaking thing isn't something that would show up until much later... I guess I was just wondering if it could be something else or if there are other things I should be waiting for to show up before I freak out too much...

So I guess my questions are:
Are there other possibilities other than pregnancy that these could be pointing to that I'm not thinking of?
And should I wait to take a pregnancy test till next weekend if my period doesn't show up or should I take it now and get it over with?
