Seeking advice or well anything.

[MarineWife93]

Hello, I am new here though from reading threads already posted felt it was a friendly place I could come to seek some help. My fiancee and I have been trying to decide if we should TTC, but before a decision could be made I realized I am 15 days late. I tested this morning for the first time and it came up negative, I have never been more than a couple days late and have been feeling not myself; I am constantly using the restroom (my fiancee pointed it out it me) I have been sleeping more than usual or wanting to sleep, and I have been getting nausea's and at times dizzy. I want to go see a doctor but feel I should wait and do another hpt first. I'm not sure what to do, I do not have any children so I have never gone through this before.
