Is Cannabis an option for nausea?

F.K.😻

So I practice Rastafari and for this I smoke Cannabis! However i do see Cannabis as a Holy herb and medication and right now i think i’m pregnant! I have late period, nausea and other symptoms so to get rid of nausea and get appetite i use Cannabis! Since i might be pregnant is it safe to smoke during the first few weeks of pregnancy to deal with the nausea or should i start using oils and edibles?
