Hi, I have a retroflexed retroverted uterus, I was wondering if it could have impeded the results of a recent ultrasound I had three days ago (6 wks since my last LMP) The tech said that my endometrium is thickening but wasn't able to see a sac. I am having blood tests tomorrow to check HCG levels etc. All Hpts are positive and my symptoms of pregnancy are very intense much worse than my first pregnancy 3 years ago. I feel pregnant but not seeing a sac was very upsetting, is this normal? Thanks in advance
