Hcg drop then rise (updated)

I have had a rollercoaster of emotions for the past almost 3 weeks. I was told by a nurse at 4weeks that 55 was way too low and that I needed to go to ER to get checked out. I was so upset but did some research and decided not to because that number seemed ok to me. Then 2 days later (4w2d) my hcg levels were 82. Doctor told me this time that it was an okay increase. Two days later (4w4d) it dropped to 64. He told me that I was miscarrying and to expect to bleed in the next week. Well one week later nothing had happened. I got blood work at 5w4d and it was 284 and again 6 days later. This time it was at over 2900! I had an ultrasound at 6w1d and was told it didn’t look to be ectopic but since it was so early I didn’t get to see much. I’m still expecting the worse but hoping for the best. I will hopefully be getting another ultrasound at 8 weeks. 😊
