I quit smoking weed at 7 weeks pregnant

Im now 10 weeks and I’m really nervous that my baby might have brain abnormalities because I was smoking heavily for the first half of my first trimester. I also was still dabbing the first week but I quit that and switched to flower, and then quit that. I also used electronic cigarettes but I threw mine away and now I only use my boyfriends a few times (puffs) a day. I’m freaking out that my baby will have defects because of my selfishness in the first trimester. Have any of you gone through anything like this? Is all of the scientific fear over vaping and smoking weed legitimate? I’m glad that I quit for several reasons but I really hope that I haven’t caused damage and I hope these fears are just in my mind. I want the best for my baby so I’m very nervous.
