Hi stotts66,counting from your last regular menstural period you may be 6-8 weeks pregnent by now and yes your symptoms did give an impression of a threatened miscarriage
. What you need to do is confirm that your pregnency is still viable and for that you need to repeat your urine pregnency test., get a urine hcg
levels assessed and see whether it matches your period of gestation and finally get an USG abdomen and if required transvaginal ultrasound
done to see for the fetal heart beat and hence fetal viability. It is important that you confirm you have a viable pregnany at your earliest as missed abortions if retained can lead to serious complications later. Take care and hope for the best.
