I had taken 5"digital blue" prgnancy test in early June, because I had missed my period in may(I have never been on birthcontrol) a couple of days after I took the pregnancy tests I had heavy bleeding with some tissue that passed from my vagina, back pain and excruciating cramps that lasted about 6days. I didn't get a check up because I had no money or insurance at that time. I had just drove to a clinic and they told me that some bleeding was normal. So I didn't worry about it too much. Now last weekend August7th 2010 I went to get an ultrasound and I'm not pregnant,I have an OBGYN appointment next week, I want to know if they will be able to find out if I did have a miscarriage and or if the "digital blue"pregnancy tests were wrong?

An ultrasound will show nothing in the uterus if all products of conception were discharged.
