CLEAR BLUE. OPK as pregnancy test PLEASE HELP

I’m currently 13 days post ovulation I took a test at 7 days post ovulation and got a BFP even though it was early my line was VERY dark! So I decided to use my opk instead of running to the store because OKP pick up both LH and HCG SURGES my question is IS THIS A POSITIVE? IM ASKING BECAUSE MY blood HCG WAS AT 54 at 9dpo and I got another blood HCG ordered yesterday and I want to be 100% sure my line is getting darker and not lighter ( I don’t want to miscarry and I’ve been a nervous wreck) this is my first baby and I’m so scared because I don’t want to lose him/her I already told my mother in law I’m preggers by accident and I don’t want to have to go thru a miscarriage pls help is this a dark positive or faint positive?
