Am i pregnant?

Hiya, me and my boyfriend have been trying for a baby this last month after having a miscarriage in July. We had sex right through fertilization and Ovulation and the last week i have noticed my boobs have gone bigger and hurt when i touch them. today i have also got a very high temperature with a bad headache, feeling sick but cant be sick, my leg left at the top started to ache and i had pains in my stomach which come and go, it also feels bloated. I also had white discharge when i went to the toilet about 5 minutes ago. does anyone know if i could be pregnant or is this just my period coming because i am due Saturday? x x x
