Not as far along as i was told

Baylee

Went to the er last night due to dark red blood and some tiny clots and i thought i was 7 weeks and 4 days when it turns out to be I’m just under 6 weeks pregnant.. however, they did see a fetal pole and gestational sac. I’m not sure what all the means. how could that be? I just can’t wrap my head around that Anyone have any insights? Or had this happened to anyone before?
