Hello, I am a 25 yr old female just found out I'm pregnant I'm almost 15-16 days dpo and got a light posiitve on my pregnancy test.. im worried because in the past week I've had one tablet of bromazepam 3mg and I read it can cause abnormalities to the fetus... would 1 tab expose me to any risk? Tell.. thanks!!

It is unlikely the single tablet would cause harm. Some women will remain on similar drugs in pregnancy if the need for them is greater than the risk to baby. Certainly if it is not truly medically necessary it should not be used in pregnancy as there are risks associated with it.
Congrats and enjoy your pregnancy... wishing you a smooth journey!
