Pregnant Stoner

Is it safe to smoke weed at any point of the pregnancy? I actually need some advice on it my best friend/Baby daddy/boyfriend left me because I didn’t want to agree to going to live with his ex girlfriend who continuously ask him for sex when or without me around he knows how I feel about it how I’m not comfortable and he gets defensive and upset because I’m not seeing his side of things it’s a whole lot of bullshit going on atm

I would REALLY appreciate it if someone could answer that on spot 😂
