What Causes Blood Discharge After Taking Duphaston And Aspirin During Pregnancy?

Hi. My name is Hope. I had an early miscarriage in November 2014 and then got pregnant again recently. My last period was 15th Feb 2015. Both times, the pregnancy has been after clomid and FSH treatment. My gynaecologist put me on duphaston, aspirin and an antibiotic after I got a urine infection. I have been having bloody discharge but with no cramping. Is it ok?
