Hello, If you have regular 28-30 day cycles and have missed a period, you should get investigated further since the home pregnancy test is negative. I would suggest a serum beta-ChatDoctor title assay along with a trans-vaginal sonogram. If pregnancy is excluded, you need further investigations like hormonal profile, general check up, blood counts, urinalysis etc. In the absence of pregnancy, a missed period could mean hormonal imbalance caused by several factors like sudden weight changes, stress, infections or certain medications and once everything is clarified, a period may be induced. Hope this helps.
