Second Ultrasound 6 Weeks

I had my second ultrasound today at 6w. My first ultrasound was last Monday and we saw a gestational sac exactly where it should be. I’m 6w by LMP and measuring 5w4d, no fetal pole yet, but there’s a yolk sac. She said I should see a fetal pole in the next few days. I go back next Monday. The cyst on my left ovary went from 4.5 cm to 5 cm (the size of a lime). She said that my ultrasound looked so good that she didn’t feel the need to check my HCG again. She said everything is looking perfect so far. 5th pregnancy, no live births, history of MC and ectopic.
