False positive?

I had unprotected sex 4 weeks ago and had a small amount of bleeding a couple of days later and nothing since so I took a text last Saturday (7 days ago) and it was a faint positive. But when I’ve taken more they’re all negative. I took one the same day as the positive and the rest throughout the last week at all different times of the day and none of them are positive. I have symptoms but I feel like they’re all in my head because the tests are coming back negative. Has anyone else experienced this and have actually been pregnant?

i have my doctors appointment on Wednesday but I’m going insane waiting for it
