Duphaston

Hi Mommies, question lang. Nireseta saken ni Doc duphaston nun nalaman namin na preggy ako ng 6 weeks. Nagtake lang ako nun for 7 days as prescribed by my OB. Then kahapon, i'm on my 10th week, sumakit yung puson ko na parang magkakaperiod, but no bleeding naman. My OB advised me to take duphaston again. Okay lang naman yun kahit i stopped for about 3 weeks taking duphaston?
