No Mens After Db10

Hi meron na po ba dito na nag clomid and then nag db10 or provera tapos di nagka mens? Sabe ng ob ob ko dapat in less than a week after i stopped db10 dapat may mens na ako. I'm on my 6th day na walang mens and i took pt negative naman. What could be the possible reason kaya aside from pregnancy kung bakit di ako nagka mens? And may chances ba na di pa nabasa ang result ko ng pt? Sumasakit ang puson ko legs ko and i always feel tired. No spotting or discharge. Pls help
