Should i trst again ?

One week after my missed period I tested twice with first response tests and get both negatives. A week after I tested again because my period didn’t show and this time I tested with clear blue and it was positive. The next day I tested again with clearblue snd it was positive. I dont feel pregnant. No nausea or vomiting, a little fatigue but thats about it. I made a doctors appointment but they won’t see me until im further along. Should i test again with first response tests? Or am I pregnant? I have been trying for almost a year so its hard to believe the positive test.
