Faulty test!!

I know this is a faulty test I get that but I took one today because my doctor said I have thickening of the uterus lining and prescribed me medicine and I googled into it and it said that you can have thickening of the uterus lining

when you’re 1-5 weeks pregnant and I don’t want to take the medication if I am pregnant so I saw a VERYYYY faint line you can barely see it through the pictures but you see it more inperson could it still be positive even though it’s a faulty test or no?
