I am 40 yr old married without any children, taken Deviry 10 mg on D-16 to D25 of my last period (LMP December 6, 2015) and now 20 + day sI stopped Deviry pills but no period, only brownish spotting for 5 days during urination. I have hypothyroid and on thryroxine 75 mcg per day.I have early pregnancy symptoms such as nausea, food craving, light headedness, fatigue, dizziness, mood swings and constipation.Please suggest how long should I wait for period or should I go for a home pregnancy test.Thank you,Bobbie
