I'm so scared I don't know what to do

I'm 5 weeks and though it was OK to use salicylic acid because there's nothing written on the cream but my doctor told me to stop right away. I was using 2 % neostrata. I'm scared and I cried all day because I didn't know that and he scared me so much I didn't know. Worst, I've used ketrel (tretenoin) cream for years and used it about 5 times while I was pregnant.. I don't know what to do, I'm so scared... Should I make an abortion? My doctor didn't help much.. I just want to cry all the time cause I want a healthy baby and maybe now it won't be because of me. Shit. Could anyone with experience in this help me?!? I'll make another appointment to another OB to search a little more on the subject. I had all these questions and my OB showed a little hurry for me to leave, not letting me clarify all my doubts. He only said that the recommendation was only to make abortions in case of oral isotretinoin. I was so happy now I'm so so sad... I only put it because I didn't know I was pregnant. The day I missed period I stopped using tretenoin... Two weeks after the conception. But the salicylic acid I just stopped 5 days ago and used it all the time and all over my face... Sorry for the long text but I'm so scared.
