You need to speak to your doc/midwife. Please don't go taking any anti sickness meds without at least discussing it first. Also if you're in the uk you'll get medication for free xxx
Try half a unisom with 50mg of b6...I that doesn't help your dr can prescribe a nausea med.
Also lemons in your water helps. Or takin fresh ginger and pouring boiling water over it, steep for 5min then sip away. Both lemon and ginger help ease nausea
