Sitting on pins and needles...

Well ladies as of today I am 6 weeks 1 day...and it's been one hell of a journey already...not a pleasant one... I'll start with my hubby and I have been TTC for 26 months. In May my doc did a HSG test, she did NOT do a preg test before. Well 6 days after my test I had a hunch and took a preg test...IT WAS BFP!!!! The following day I saw my doc and she was just as shocked as I was. The ultrasound showed a gestational sack measuring at 5 weeks 1 day...today I went in and we saw a gestational sack measuring 6 weeks 1 day with a little white speck. The tech said it was either the yolk sack or embryo..I don't understand why she couldn't tell which one it was...my HCG levels 5/28 were 2,305 and 5/30 they were 3,094. Doc was not happy with these numbers but said based on the ultrasound it seemed I was progressing...I have switched doctors and start seeing my new one this coming Tuesday...the anxiety is just killing me...anyone else having a rough start?
