Type of birth control pills: Necon 1/35

My doctor prescribed me them (along with iron pills) because they discovered I was anemic (iron deficient).

I'm currently taking the pills everyday at 3pm, but I was advised to skip the white inactive pills because I'm not supposed to have my period. Am I still protected?

I had sex without a condom on January 26. My boyfriend did ejaculate in me.

I have been taking these pills for over a month now (probably two), but only a month ago was when I started taking them at the exact time every day.

What are the chances of me being pregnant? Am I still protected even though I don't take the last week of sugar pills?
