Faint line steady for days

I got a positive first response and strip test, positive digital the next day. At the doctors office four days later it was negative, home the same night it was positive but faint. Blue dye a day later was positive and multiple strips are faint but positive. They aren’t getting lighter but aren’t getting darker either.

I would be 4 weeks today so still very early. First positive was last Sunday 4/21. Blood work Monday and Wednesday for beta trends.

Anyone with anything similar? What was the outcome?
