Last week I took a pregnancy test and it came back negative. Lately I been nauseous and tired a lot. I should have my period in the next two days but I’m not showing any signs of it starting. ( normally I’m bloated oh get that “period” smell right before ) has anyone had a negative test before but still ended up being pregnant?

***update. I just took another test and it came back negative :(. I would of thought me being nauseous like I have been my levels would be high enough to tell :(
