good eve po.

Ilang days na po kasi akong nanghihina. Every morning nasusuka ako and may times wala din gana kumain. May times din na sinisikmura ako at heartburn. Nag pt ako pero negative naman. I'm expecting my period in 4-5 days. withdrawal method kami ni hubby. What could the possible cause of this? Im so confuse. Di ako makapunta sa ospital because of pandemic and I can't find ob gyne on facebook. Thank you.
