Biglang na low sugar

Meron po ba dito na mataas yung result ng ogtt tapos pinagdiet then pinagmonitor din using glucometer? Ganun po kasi pinagawa sakin, bale 2wks ako pinagmomonitor but unfortunately 2nd week na ko nag start kasi kakadating lang ng order kong glucometer from lazada. Nung 1st week nagdiet talaga ko, brown rice tapos puro wheat bread. Tapos nitong 2nd week nagmonitor na ko nagulat ako kasi bumaba talaga yung result, as in mababa to the point na "Lo" na nakalagay. Sa saturday pa po kasi kami magkikita ng ob ko. Any suggestions po? PS. 36 weeks pregnant a
