I had sex for my first time two days before my period. I am on the pill, he used a condom, and he did not finish inside me. My period has not started after taking my first two white pills (period pills). What are the chances that I am pregnant?

Probably very slim. I never start my period until the last white pill out of the 4 that are in my birthcontroll.

Assuming that he put the condom on properly, you are definitely safe from pregnancy. Although abstinence is the only way to be 100% safe from pregnancy, using two contraceptive measures is extremely close to that 100%.

Make sure you relax though! Stressing about anything can significantly delay your period.
