scared asf

Sooo I looked at glow and my period was supposed to come two days ago which it still haven’t. And I went the the doctor and tried to get a pregnancy test and they said just wait because I still had 2 more days for it to come on. I’m scared rn because I’ve had symptoms like nausea cramping and back pains but I also had a uti and they were saying those were symptoms of my medicine. Can somebody please tell me what they think
