Morning Sickness

I am on my 13th week of pregnancy and I feel that nausea/vomiting is slowly going away, though I still have no appetite. Is it normal na mawala na morning sickness at 13 weeks? My OB told me kasi na possible din cause ng pagkawala ng morning sickness yung wala ng heartbeat ni baby. Also, my OB advised that my next check up is on my 20th week (last check up was when I was at 8 weeks) if no bleeding/spotting and pain sa puson area. Ganun po ba talaga kasi alam ko dapat every month yung check up. #1stimemom #firstbaby
