Hello I have been trying to get pregnant for two years and finally found out I was pregnant I'm 9 weeks pregnant now but my ultra sound measures me to be 6 weeks.they can't find the heart beat and Monday my HL were 5800 and Thursday it went down to 5500 the doctor said I would miscarry but I still have no cramps, no bleeding. How long does this take . Should I still be having symptoms of being pregnant??? Is it possible that my baby is growing just but very slow...can somebody Help me.
