5weeks 5 days

Sino po relate, im currently 5weeks & 5 days. Based on my LMP. Positive PT. I was sched for ultrasound on Oct 2, 2019. I feel cramp on the left side of my lower abdomen. May OB advised to take Isoxilan and Duphaston for 3 times a day. No spotting. Through IE, she checked if im experiencing ectopic pregnancy but luckily na rule out naman. What can you say about it.Is it safe to take such med? Thanks in advance.
