Kapag po ba may yellow discharge, meaning may uti ? pero hindi naman po ako nahihirapan umihi.......

You're 8 weeks nah, have you done any laboratory and ultrasound tests? On my 1st tri my OB let me go through tests like HIV, syphillis, hepa, CBC, Urinalysis, bloodtype (i have a rare bloodtype) even papsmear, TVS ultrasound... If hindi pa, might as well you go through all that with OB's order (depende sa OB mo din) para may baseline data ka sa bubuntis 'coz you might experience other prob along the way pag lumalaki na tiyan mo at hindi lang yellow discharges. :)

could be bacterial vaginosis or yeast infection
