Really down

After getting over a chemical pregnancy in May I finally got my period July 19. We've had sex most of the month. I believe I ovulated at the end of July. I took a test tonight (6 days before my period is supposed to come) and it was negative. I want a baby so badly. My nipples and boobs are slightly sore, I've been exhausted the past week (could be due to school starting), and I'm bloated. Im praying I'm pregnant instead of PMS symptoms. Someone give me some hope
