despite being so careful with my significant other, i still find ways to convince myself we weren’t careful enough. (condoms and withdrawal together)

i’ve only been sexually active twice and both times i knew that realistically there was barely any chance of a pregnancy, however; my anxiety yields to no amount of logic. i am not on any form of birth control as i know my parents expect me to wait until marriage. i am 18 though and completely in love with my boyfriend. i don’t know how to ease my nerves privately.

would talking to a doctor about birth control expose me to my parents? should i talk to a doctor about anxiety medication? please help.
