Does having a tipped uterus affect ultrasound for pregnancy? at 4 weeks conception would the dr. see anything?

Not really, heart: "tipping" of uterus is how uterus points inside body and doesnt affect pregnancy. It may affect ability of ultrasound to see early in the pregnancy but minimally so. For example, if your uterus is retroverted (pointed to the back) it may make it a little harder for ultrasound to see as uterus is farther from the probe (particularly if theres bowel in the way as well). Can see sac, heart beat.
