Hello, I had an embryo transfer on 06 july and my hcg was negative on 21 july. My doctors started 10mg Northisterone 3X per day for 5 days starting 22 july. Today is 31 july and no periods. Can i be
pregnant? Should i take a urine test? Or is it due to progesterone shots and other fertility drugs that my periods are delayed? My last 100mg progesterone shot was on 21 july. I always get my periods on time. My LMP is 19 june and my cycle is always 28-30 days. Should I get a ultrasound or just wait for my periods?
