took my anxiety medication while pregnant

let’s begin with , im 12 weeks pregnant. i was diagnosed with bipolar, depression anxiety and borderline personality disorder. i have been doing great so far during this pregnancy and a lot of my depression and some anxiety has cleared up! but last night i had such a horrible anxiety attack , like one i haven’t had in a very very long time. I stopped taking medications when i found out i was pregnant and it was quite easy as i was just diagnosed and prescribed them not but a month or two before i fell pregnant. anyways, back to last night i had taken .5 of my kilonopin and 10mg of my valium. after taking them and i was getting back to myself i began to worry and read up about all the side effects and now i’m extremely scared. should i go to the emergency room to make sure all is okay? and do you think my baby will have birth defects now? if god forbid he/she did, when would i know? im so scared y’all );
