Im want to apologize in advance.

My lmp was 11/10/18 35-39 day cyle. My on and I are pretty sure I ovulated an 12/6/18(it matched my hcg levels. I'm 37yo with pcos, and always considered high risk. I got a positive (many positives) on hpt's starting on 12/21/18. I had the serial beta done for a week and looked great. Once my levels got to 1578miu/ml my ob scheduled my first ultrasound for 1/7/19. We walk into to building (cue full blown anxiety attack as I've had 2 previous mmc's (one with bleeding one with no symptoms except my son told me I miscarried...weird) we go in for the ultrasound and we see the fetal pole and yolk sac. My ob said to come back in 10 days for a recheck. From the time of this ultrasound I've had normal symptoms that have started to decrease in severity but not completely disappear I had a small bit of pink blood one time 2days after my ultrasound and the advice nurse said it was normal in the earlystages(never had bleeding with any pregnancy) They said as long as I'm not bleeding like a period and dont have cramps everything is fine and normal. FF through the week and a half to the second ultrasound today (cue the anxiety attack...again) I go in and they wont tell me anything!! They wouldn't even show me the screen(I had to really put my foot down. Once she showed my i asked why i didnt see anything and all i got was "I'm not a doctor and your uterus might be tilted" (I've never seen her before) and she seemed to have rushed through. I saw her type SABC HEM on the screen (if anyone knows what that means I would greatly appreciate a definition). She then tells me that the doctor wants to do an ultrasound but changed his mind...whatever. we go to the exam room and he tells me that I'm having a miscarriage...QUESTION...how do you go from seeing a yolk sac at was is dated as 5w 3d and fetal pole to seeing absolutely nothing, but a possible tilted uterus at 7w 3d EDD being 9/3/19?? The ob who I met once before for 5 min was very apt to say "I'm not trying to put words in your mouth or make you decide right now, but I think you want the D&C. I already had 2 previous ones...no thank you and why would you do that procedure when they usually don't do it for anything less that 8 weeks...per the doc...He seemed really quick to want to schedule it. He never said anything about doing a second ultrasound to double check or anything. Is it a bit odd that if I dont have any symptoms of a mc...no bleeding, no major cramping, that I'm told I'm having one without checking my levels etc? So far I still have boobs that are sore as hell right now compared to earlier when they weren't. Mild nausea (had severe nausea with my now 17yo nothing with my now 14yo or with my late daughter) the only think that stopped was my cravings for taco bell (had that with my 14yo). IM SO SORRY IN ADVANCE. IM TRYING TO WRAP MY HEAD AROUND ALL OF THIS. Any help with advice or insight would be greatly appreciated.
