Around 7 weeks, nausea = no joke

I am around 6w6d or 7w2d (not too sure cause app and dr tell me diff dates😄) however this nausea is NO joke. I thought I was in the clear but it hit me like a train this weekend. For some reason it’s just in the evening but the past two days I’ll feel unmanageably hungry around 3-4pm, eat, and then feel soooo sick the rest of the night. Also, I’ve woken up 2 early mornings already because I feel light cramping and so nauseas. I’m already so in love with my blessing but wholly mackerel. Any other ladies experiencing weird nausea?? 😭
