Ok, i was fertile on the 5th and 6th of september and had sex both days. About two days later i began to sleep, feel full, nipples hurt and white crust in them, my areola is getting darker and those little bumps around my areola are getting bigger and darker. I have been wanting to throw up. I have experienced alot of pregnancy symptoms, yet today four days late my period is here it is lighter than it has ever been but its not heavy enough to put on a tampon or anything like that. How many days is this supposed to happen before if pregnant? See i have been trying for a long time and all of the other times i had one or no symptoms and i even find myself thinking of baby names. Can i be with child? Please help!!!!!!!!!
