Bloating at 5wks

Kristin • 27 married army 2 girls ( 3 & 8 ) expecting our 3rd and final princess. recent miscarriage (04/24) we found out our rainbow is due 02/13/18 :)
Before we found out I told my husband I feel so bloated it hurts my back and makes it difficult to sleep. Doc said I can take gas meds. Will this help the bloating big time I look and feel rough.
