Weed in early pregnancy

Okay okay don’t mom shame cause I’m looking for actual facts- not opinions.

So I am 8 weeks pregnant, and I smoke weed- actually THC from a dab pen. I found out I was pregnant and I stopped smoking it regularly. Occasionally I smoke- really just a couple of times when my nausea would get unbareable or my anxiety would act up. So It’s only been like 5-6 times in the last month where I use to smoke everyday.

My question is, now I’m worried about any affects this could have in early pregnancy and development of my baby.. I’m not smoking anymore, I won’t be for the rest of my pregnancy but I’m worried that maybe I’ve already caused problems with baby..

We had a perfect ultrasound at 7w2d, I’m having all the symptoms, the aches and pains, everything is going perfectly!! 💛

I really just want to know what are some possible side effects of smoking so early on..

TIA 🙌🏼
