I went to the er a few days ago because I was having extreme back problems somehow they asked me when was my last period I told them I was late and they did a pregnancy test that came back Positive . They wanted to do a ultrasound vaginal and regular because i said i was having lower back problems and i was cramping a little bit but not bad to where i wanted to be concern . Well that’s the ultrasound and my hcg was over 6000. I’m 5 weeks 4 days . Er doctors really didn’t explain things well to me .
