Ultrasounds

So I just have a question for anyone who is willing to answer. I had an ultrasound on December 29th and I was 5w1d,or that's what the gestational sac was measuring and there was no fetal pole. Gestational sac was 5mm at that point.

The next ultrasound I had was January 12th and the gestational sac grew to 13mm and there was a fetal pole and a CRL of 4mm. So everything progressed, but not for two weeks passing is what the doctor said but she was not ruling this a miscarriage she said and told me to come back in another 2 weeks!

My HCG levels were 6,437 with my first labs and 8,978 with my second labs. Going to get more labs done on Tuesday to see if they have gone up more. I do not feel like there is anything wrong. I have had no signs whatsoever that there is anything wrong. Could it be that I am just earlier than I thought and that I just ovulated later than I thought, is that a possibility? I am very hopeful and have faith that this pregnancy is progressing and is good. I have had two losses and they completely broke my heart and I cannot handle that again. I need some hope and some good stories where this has happened to someone else and they had a healthy normal pregnancy.

I feel like if I was having a miscarriage or there was a threatened miscarriage then it would already have happened since over 3 weeks has passed sincey first ultrasound and it's been another week since my last one and there are no signs of any issues. I know sometimes you don't have any, but I feel really good about this pregnancy. Please give me some hopeful stories or some good insight on things that have happened like this for other people! Please end some prayers also if you pray or whatever! Thank you!
