idk what to do...

So long story short, i have pcos, we tried for a baby in july, i had a wierd period in august (on time maybe a day or 2 late) (wierd meaning very very light and kind of mucusy tmi--sorry) i have not had a period since. once i had my august af, we decided to atart thinkin abou ivf. but i havent had a period since than.. and for about 2 weeks now (maybe a lil longer) i have been having pregnancy symptoms like consipation, heartburn, nausea, and gassy and an increase in appetite. i went to the gyno thursday which was absolutely no help, they ran another pregnancy test (after i had told them i have taken planty all negative) i would like to go to a place and basically request an ultrasound but i have no idea of any place that you can go amd request that. so idk what to do now... any suggestions would be greatly appreciated..
