Smoking while pregnant

I don’t want a lecture about this being bad. I haven’t smoked weed since I found I was pregnant. But a few people have told me it’s ok to smoke a little, to help with nausea and to help you eat. Is that true? I used to be a heavy smoker but since I got pregnant I’ve been a little paranoid to do it. Would it be ok to take a few hits so I can actually eat something. I was eating good but now nothing sounds appealing and I just don’t want to do it. I am currently 11 weeks and this just started happening. I have had this vape pen with a THC cart on it for a while, that’s what I would use.
