Line progression and first beta hcg at 12dpo

Got my first beta hcg at 12dpo (thursday) and it was 93. and progesterone was at 136 nmol/L (taking progesterone suppositories). The first 4 days 9-10-11 and 12 dpo my lines barely progressed at all and i was for sure i was having a chemical (i even stopped taking my progesterone for 24hours🤦🏻‍♀️) but they friday at 13dpo and today at 14dpo i see my lines getting darker i think?!! what does everyone think? hows my line progression especially in the last 2 days? and my hcg?

Also **ifff** this was to be a good pregnancy why was my line progression non existent for 4 full days at the very beginning?!
