Re: Rising HCG levels but nothing on u/s...
It's just too early to reasonably expect to see much. Yes you might have seen a gestational sac and possibly even a yolk sac but it's not likely. I was lucky enough to see both with this baby at 4w5d but I had sky high betas so probably implanted a few days early. When do you go back? I would think you can expect to at least see a sac next week and embryo and possibly hb the week after.
