Prayers please

I’m trying for my first .. it will be a rainbow baby .. I was due for af this past Monday .. I took preg test day Sunday Monday all positive .. I took one this morning it said pregnant .. I just took one now (bc I’m crazy) and it said not pregnant .. I go to get blood work tomorrow .. could it be a chemical pregnancy or could it be because I barely peed on the stick and I’m super hydrated today
