hCG too low 😪

So, I had bloodwork done today, and at 4 weeks and 2 days I was told my hCG was at 153. The doctor stated that that was entirely too low. Of course I have to come back in two days and see if they double. I’m a bit discouraged right now. It seems like I can never make it past 5 weeks. I’m hoping for the best but still expecting the worst. Anyone else been in this situation and their hCG doubles the way it’s supposed to? Prayers would be greatly appreciated.
