A week late & neg hpt

So I'm a week late. I have been irregular in the past, but lately pretty consistent. This month....a week late. I've take 3 hpt (three different days - late day 2,4,5). I'm having the symptoms - bloated, moody, cramps, sore breasts just started, the constant need to just eat something. I'm also having a clear discharge. Sometimes it's watery, sometime a little bit thicker - I'm constantly thinking I've finally started only to realize, it was discharge. And it happens multiple times a day. Now, normally, I have most if not all of these for a couple days prior to my period. This time around, everything but the sore breasts, have been going on for a week and a half. Has anyone gone through this?! I'm getting worried that something is wrong.
