Pregnant or hormonal imbalance.

I work night shift as a nurse. I recently took a vacation from July 14- July 23. I was back on a normal sleep routine. The hubby and I baby danced on the day I was ovulating.. Which was July 17- July 23. I am now back on my normal routine of staying up all night working. I had my annually Pap smear done July 23, which I bled some. My breast have been extremely sore for about two weeks now. I am having this white creamy discharge that doesn't have a smell (never experienced this discharge before). Considering I'm a nurse, I know it's not a yeast infection. I have been extremely moody and irritable. My husband thinks we have "drifted apart" because we have only baby danced 3 times since my July 23. I don't want to be touched, very bloated, cramping on right side, hungrier than normal. I've also been kinda foggy headed. I took a test two days ago and it said negative. I was supposed to start August 5 but I haven't. Pregnant or hormonal imbalance?!
