Line progression??

Alexis

Hello! This was my 3rd round on

fertility drugs

. I did the trigger shot with 5 follicles.

I took a test yesterday 8/22 at 9 dpo with a faint positive pictured. Had blood work and hcg was 10 but they are saying pregnant. I go back Monday to see if it’s doubling.

However. I tested today and got a dark line at 10 dpo. Is this a good thing? Could that mean it is doubling?
