Weird feeling on my belly

Hi mga mommy. I'm at my 17th week now, currently under maintenance ng isoxilan and heragest. Last check up ko nung june 4 and okay naman si baby. Last night naka experience ako ng pain sa belly ko, saglit lang nawala rin agad. Then after nun until now, parang may pressure sa belly ko and parang may malalaglag na feeling. Is this normal po kaya or should I contact my OB na? Sa july pa kasi ang balik ko sa doktor. #1stimemom #advicepls #firstbaby
