Talk me of the spiral ledge!!!

Backstory, miscarriages in 2018, 2021, baby born April 2024, chemicals October 2024, January 2025, February 2025, pregnancy now. Technically 6 weeks yesterday. Had blood drawn on Tuesday afternoon around 3:45 hCG = 11,069. Had early ultrasound yesterday because of higher than my normal levels, and worry for ectopic. I know the numbers can vary so much! Gestational sack measuring 5 weeks 2 days. Had blood drawn today around 4:30 hCG= 19,546. It didn’t quite double so I’m freaking out just a little bit. Tell me it’s normal. Tell me it’s not normal. Tell me I’m crazy. I don’t really care, just tell me something. Haha. I go back on Wednesday for another ultrasound but that’s a long time away, and I need to stay away from Dr. Google!
