Hi There Doctor - I Took Fertomid 50mg In My

Hi there doctor - I took Fertomid 50mg in my cycle last month - I should have started with my second cycle on Sunday 25 Sept, this morning I did a pregnancy test with first morning urine (29Sept - 5 days late) the test came out negative.
I moved from departments and experience some stress at work.
Could I still be pregnant or do you think it has to do with stress I am experiencing?
