Please pray for me! I'm so lost

I am 4+5. Last night I was getting a haircut, while sitting in the chair I started getting strong, sharp, menstrual-like cramps mixed with what felt like gas cramps. I could barely walk! I never felt anything like that with my first so I decided to go to the ER. We ended up doing a transvaginal ultrasound. They told me they could see a "sack where there would have been a baby but now all they see is debris." The tech told me my scan looked abnormal to her. I lost it. After waiting 6 hours in ER I had convinced myself they would tell me it was just some gas and to go home, that everything is okay. The nurse practitioner came in to tell me that "at this point she's 90% sure this pregnancy is not viable, but it's possible you're just way too early on." My hcg levels were 150 and I go back Saturday to retest my levels. I'm just heartbroken and so incredibly sad, I feel hopeless. Please, please, please send prayers and good vibes.
