So I went in for my first appointment thinking I was at 6 weeks but only measured 5 weeks. My cycles are never consistent and this past one lasted about 10 days so it would make sense. My doctor saw the gestational sac but nothing else. From the pictures it almost looks like there is a possible yolk as well, what do you think?

I have had a previous miscarriage so this has me nervous, especially with few symptoms. I had mild abdominal cramping and still tender breast unless I have a bra on. My hcg levels on Monday was at 1312 and last Thursday at 402.
