Montgomery Glands/Pregnancy?

In July I thought (not even sure) the condom broke so I took plan b a week later I got a full period and then a month later about 32 days I got another full period. I havent had since then and I'm not due for my period until next week but I have mild cramping bloatedness and my are browner than usual and it seems my montgomery glands are more present than usual. Is this all possible without being pregnant? I am going to take a test first thing tomorrow I just wanted opinions.
