I'm so embarrassed...need to vent..

I am 32 weeks pregnant and have a autoimmune disorder "antiphopholipid syndrom" which causes blood clots especially during pregnancy which can lead to organ failure, miscarriages, or still birth. I went to the ER last night after waiting all day for my kidney area and chest to stop hurting. ( History: Oct 2017 I had blood clots in my kidneys that made them rapidly fail for 12 days after getting birthcontrol out.. it was extremely painful. I thought I'd never forget that pain...) well last night I thought I felt it again. All that pain must've caused me to have Braxton hicks over and over all day long(one every 6 min for 2 hours at its peak in the hospital). Well, when I get Braxton hicks now my heart rate gets high and it feels like its Skipping beats. Then I get a tight pain in my chest. So of course they take chest pain very seriously and they did ALL the tests. My resting heart rate was 98 and it got to 112 at the peak of a Braxton hicks. Normal for pregnancy is supposedly 70-90 depending on weight but can be even lower during the 3rd trimester. My highest blood pressure was 144/89 but by the end of the night it was reading 115/65. They did a CT (completely avoiding the baby thank goodness) and it showed no clots in the kidneys. They said she must've been laying on parts of them which can feel like failure from the pressure? But they never gave me a answer for the chest pain and trouble breathing which I am still having. But I am so embarrassed about going to the ER at all... I felt like crying afterwards because i felt like I wasted their time and overreacted. Maybe it's the hormones but the doctor at the end acted like I was overreacting... just from his body language and tone of voice. I felt sick when he changed the way he talked to me after the results came back. "Nothing at all is wrong so I can see why you would worry but your perfectly fine." Which I normally wouldn't take so harshly but idk..I dont know what I'm searching for. I'm just feeling alone and embarrassed. Maybe judged.
