False positive?

Me

I am late by one day and I have done three tests. The first last night (not pregnant) one when I first woke up today (pregnant) and one a couple hours later (not pregnant) I’m on remeron that I take at night, could this have caused a false positive when I tested first thing in the morning?? I’m going to buy more tests soon, but wondering if anyone has any ideas.

UPDATE: I’ve gotten another one... can a bladder infection cause a false positive?? Holy hell I’m terrified.
