Could I really be the 1%?

Samantha
I am on the second week of my second pack of birth control, last week I took a test and it was negative, I was worried I was pregnant from the last month because I had a short bleeding period, but I guess that was my period. The last week I had sex 4 times and he cam inside me. But I take my pill at the same time everyday and have not missed any pills. But yesterday i had bleeds that was super super small and I would say reddish. I don't know if I would say pink, it was barely anything, and only when I wiped. And now it's gone. Cm is white. I am on Junel 1-20 birth control. I am on day 24 of my cycle glow says but still have to finish this week and another week of pills to finish the pack before the week of taking no pills. Do you think I'm pregnant?? Please help . And I have had kind of sore breasts
