Ladies i need help..

So yesterday i found out i was pregnant! I've been smoking weed for 6 years now , & i have major depression , PTSD & Bipolar & Anxiety.. When i smoke it relaxes me & makes everything mellow for me .. When i found out i stopped smoking yesterday.. i smoke 24/7 & this is really hard for me.. So i was sitting in the living room all panicking & worrying .. so my brothers girlfriend comes in with some weed & I couldn't resist it .. so i took a couple of hits now i feel very calm just relaxing enjoying these warm groovy vibes from the music we're jammin to .. my thing is should i stop smoking weed because of my pregnancy? Would it harm my baby? This is my first pregnancy ever & don't know much about it.. Could someone help me with answers please.
