What Causes Mood Changes And Fatigue?

My husband and I are sexually active, and do so on average 3-6 times a week. We both want to have kids eventually but not actively trying-more treating it as a if its meant to happen it will happen. Lately, I ve felt like my body has been changing in some ways that are concerning to me. We did just move and it has been quite hard to adjust as its my first time being away from home. I ve felt quite moody and have been experiencing some fatigue. I have always needed more sleep then the average Jo (8hrs minimum). I get up early with my hubby getting around 6 hrs but I usually go back to sleep for another 2-2.5 hours after he leaves or may take a nap in the afternoon. So it seems like I should be getting enough total sleep and I don t engage in much activity other then basic housekeeping and occasional walks around the neighborhood throughout the day. I also am unusually emotional. I can cry at the drop of the pin. Everything and anything can make me cry. Often times I won t even feel sad something will just come off wrong or I won t even feel inclined to cry until my husband (who is very good at picking up when I m upset) asks me what s wrong. And then I cry and he wants to know why but I can t pinpoint why I m sad or why I m crying. This is very unusual for me as I honestly never used to cry, except occasionally if I was really upset but I was always able to hold it in until I was alone (I don t like to cry in front of people) I don t know of it is just because I feel so comfortable around him or if it is on account of hormone imbalance or just being homesick... But just a few days ago I noticed a significant change in my vaginal discharge. Typically I only notice it just prior to my menstrual cycle. However, the past couple of days Everytime I pee, I have a significant amount of discharge. It is still clear and mucus like and odorless, but I don t understand why there would be such a large increase when my period is not due to come for another 2.5-3 weeks. Possibly early pregnancy signs have crossed my mind, but I have not yet missed a period. I have noticed slight weight gain, but that could be on account of differing eating habits. The year prior I was in school full time and working as well so I wasn t eating as much. Now I usually eat a full three meals a day. Could you give me insight as to what could be possible causes to my changes in moodiness and fatigue?
