Beta levels Q/can't stop worrying

RDK24

Hi ladies,

Got the results of my bloodwork from yesterday. I was 4 weeks, 6 days when the did it. They said it was 281.5 and that my progesterone was good. I think the # refers to "beta?"

Also, according to FF, I was 17 DPO on Monday.

They want me to come back for repeat bloodwork Thursday to make sure the levels are doubling and I'm freaking out, like this is the beginning of the end. I'm having so much trouble keeping my anxiety under control. I looked up a chart with levels and it seems on the low end.

 Anyone with experience on this who could weigh in/offer reassurance? I'm sorry I've been a bit of a basket case on TB so far, just beyond worried. Thanks.
