Need Some Advice

First off I have very irregular periods. When I went to my first appointment I was only measuring about 4-5 weeks on April 4th with an Hcg level of almost 7,000. The doctor thought I ovulated a lot later being that my cycles are very irregular. I went back for a second US about a week later. The tech did an abdominal US. She rushed through it and was very rude being that it was 10 minutes to closing time. My husband and I saw something on the screen but of course she did not measure it. I went for my third US yesterday. The tech was much more nice this time and actually spoke to me. The gestational sac measured much bigger than previous however did not show much, all we could see was a elongated shadow in the background. It seemed so pushed back we could not get a good visual nor any measurement. I go for a 4th US in a week and then the doctor is to speak with me afterwards about my “options”. I feel like I haven’t gotten any answers at all and at the 4th one she will try to tell me I’m not pregnant and or I have had a miscarriage and need a D&C.; I feel as if the doctor and team have not even really tried. It’s been a month and I have no answers. I even asked for a repeat Hcg level and I was told no because they stop drawing them once the levels go above 1,000. I would at least like to see if they have gone up significantly by now or if they have decreased since my first draw. Then I would at least know if they are lower then the pregnancy is not viable. I also requested for a transvaginal US being so early but I was told no as well. This is making me very upset and I have cried over this multiple of times. I have no answers and it seems as if the doctor is not trying her best either.

I’m sorry this is so long but I just need some opinions on what you would do or think.

Thanks!
