I had a tube removed a couple weeks ago (ectopic), but we are also monitoring a gestational sac in my uterus. My hcg levels are going up, but we have yet to see an embryo. Has anyone had a heterotopic pregnancy? How long did you wait before you saw a viable uterine pregnancy after ectopic surgery? Because of having two fertilized eggs and two separate implantations, we don't know when this uterine pregnancy happened, so we have no idea about dates. It's getting very frustrating.
