🌈 TTC baby #2🌈 is this my bfp? Need advice!

Hey ladies! Trying to conceive baby number 2. I’m currently 6 DPO and I decided to test. Is this a faint line? The first picture was taken within the correct time frame. The second two are a half hour after (I know without the time) but the line is definitely there and it did definitely get darker. Has anyone used this brand and it be correct before any other brand? I know I’m testing early but my cycles are wonky. So faint to see in the top photo but it was there and still drying! If it was negative it shouldn’t have showed up should it have?
