sex, the pill, and condoms.

hey everyone! i just have a few thoughts running through my mind about my sex life. first of all I could be very neurotic & I tend to overthink 24/7. I've been on the birth control Apri for almost 2 years & I've just recently became sexually active. I religiously take my pill at the same time everyday. my boyfriend & I also use condoms every time we have sex, but the condoms have been irritating me. there is always that thought in my head "what if we don't use condoms" and "what if the condom breaks" so.. if the condom does break is there a chance I could become pregnant or should I not be so neurotic? because there always is that 1% out of 100 women a year that become pregnant. Also my friend is on the same birth control and she lets her boyfriend finish inside of her.. is that okay too?
