Two test one negative and one positive

I tested when I was 6 days late on my period and then 15 days late. The first one was negative and the last one was positive. I don’t feel pregnant at all. I’ve been pregnant 6 times and I know the feeling my body gets very early on. I’m trying to get a damn doctors appointment but everything is scheduled out until January. I’m just concerned that it could be something else going on like an ectopic pregnancy or something. Should I just take a few more test?
