Salicyclic Acid (Acne)

So I have been using a face toner from Neutrogena for acne, it's called stress control.. I have been using it for years 2x's a day and last night I got the urge to look it up to see if it was safe, well tomy surprise there's conflicting things about it. I've read that it's considered "safe" as long as it has 2% or less, which it does only have 2% and then I've read not to risk it. I'm 8w6d and I'm really terrified that I've done something to risk my pregnancy or harm my baby. I've that it can absorb into the skin, but it has such a low amount there are no known effects.. Like I've said I've been using this same stuff for years 2x's a day, I'm a first time mom and worry about everything under the sun. I'll toss it starting today until pregnancy is over but I'm worried. My last ultrasound was 6w4d and my baby looked great with a strong heartbeat. I wish I would've known sooner 😕
