Pregnant or not

Okay so my doctor told me to take three birth control pills ( I never take them ) to make my period go off but she doesn't know I don't take them . But I did this one time cause I wanted to have sex with my boyfriend .. it went off and the next day I went to his house and he did the nasty , plenty of times the two days I was there . ( from today it makes almost a week ) now a couple days later I noticed a white discharge , and I never get heart burn ever in my life but I did for the first time yesterday , which I read is a sign of early pregnancy . And now I'm spotting ( light period like thing for two days ) with mild cramps . Could I be pregnant ? ( we didn't use condoms and he didn't pull out ) and it feels like I'm coming down with a cold , any info ? Help me out
