So stressed& confused

Sooo...there is a lot going on in my personal life trying to transition into a new job a lot of stress. Ive been trying to concieve for 2 months. Been keeping up with ovulation bbt cm all thay fun stuff... Ive been so sick to my stomach running out of the room in fear someone is going to witness me getting sick. My boobs hurt omg they hurt and are hard. I have no cramping back ache ect like I would if AF was coming. Which btw AF is due Sunday and still neg tests. Am I testing to early? Or is this all triggered by stress from work and the kids? Advise would be awesome. Someone thats been in the same situation....
