Participants in the intervention group will receive a brief orientation via a research team member at the time of randomization on alternate nostril breathing (ANB) and then be provided with a written and video-based instructional guide. They will be instructed to perform ANB 3 times per day for 5-10 minutes per session over a 7-day period and document their sessions in a daily symptom diary. The 7-day period will begin the following day after enrollment to allow for a full day of intervention implementation (Day 1-7).
Behavioral: Alternate Nostril Breathing
This group will receive usual care and complete a daily symptom diary for Day 1-7.

Severity of Nausea and Vomiting
Measured by the change in the Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) score, where scores range from 3-15, and a higher score indicates greater severity of nausea and vomiting.
Time frame: Day 7
