Mama, please go to the ER or urgent care ngayon na, hindi dapat maghintay until Monday kapag may lagnat, lalo na at 6 weeks ka pa lang. Fever during early pregnancy needs to be checked right away kasi dapat ma-rule out kung ano talaga ang cause. I know clinics are closed, pero emergency rooms are always open, at mas safe na marinig ng doctor what's happening with you at baby now. Ingat ha, don't wait!
