Ultrasound at 5 weeks

I have to talk to y’all about my experience today. I didn’t get it at alllll and really could use some advice. I found out I’m pregnant, it’s fairly new about 5 weeks. My previous pregnancy I bled from 4 weeks to 16 weeks and then my water broke due to medical negligence at 21 weeks and I had my daughter at 26 weeks. I had to get scans done all the time to monitor my sch prior to water break and I am just paranoid. This time I spotted 1 time for less than 12 hours and it was very clear that it was implantation as it stopped and hasn’t happened since. I’m of course anxious with PTSD because of my last experience, and brought it to my doctors attention that I can’t feel any excitement about the pregnancy because I’m just so scared at all times. She decided we should do a ultrasound today. I’m 5 weeks, I asked her can’t we just wait until next week? She insisted that we do it today since I was high risk last time so I agreed to it. The entire time I was in the scan the tech was basically like “why are you here? It’s too soon to see anything.” I’m like idk my doctor wanted a scan? She’s like yah well nothing will show right now. I’m like I’m pretty sure my daughter had a sac at least at 5 weeks when we looked due to bleeding last pregnancy. I pulled up my paper work and it was 5 weeks exactly and there was a gestational sac. I looked on here and so many girls had scans and ultrasounds at 5 weeks with a pic of the sac and everything. This lady told me there’s no way anything will ever show before 6 weeks, my doctor does not understand how internal ultrasounds work and started questioning “what was so high risk about your last pregnancy?” In a sarcastic tone. I don’t know if it’s my hormones but I feel annoyed by her. She didn’t show me the screen once or express any kindness even after I said “I am very anxious” “do you see anything at all? Please ease my mind” …she was like “I can’t tell you anything. It’s too soon anyway. You shouldn’t even be here until 6 weeks. Grrrrr. Thanks for letting me vent.
