Could The Delay Still Be Due To Pregnancy When I Took Norgest Twice Daily For Missed Periods?

Hi doctor , I took norgest tablet two times per day, because my period is late for two months. My last period was on January 26th to 29th. Today it s April 09. I had foreplay with my husband on February 7th ( did not have sex with penetration) I did an hcg test once and it was negative. Before this my period cycle was 35 days or 40 days.
