Pregnant When Using Birth Control?

Hi

i am 20 years old.


I have been on birth control for 6 months. My birth control is estrostep (28day pack).

I just finished my period a couple days ago just as it should come. Everything was on time. A couple days later, me and my partner were fooling around. We did not have sex. He just 'played' with me with his fingers.


A few hours later, I had a little bleeding occur. The last time I had sex was 2 days before my period (exactly 9 days before breaththrough bleeding occured).
Could this little bleeding be breahthrough bleeding as a warning of pregnancy?
Trauma to the vaginal walls?


But could pregnancy still occur from having sex 2 days before expected period and still recieve a period.



Because what i'm thinking is that this could be breathrough bleeding and could be pregnant from having sex 2 days before my period (and I still got my period)

please help...Please

thanks =)

by the way, me and my partner use condoms everytime we get intimate
