(Top picture) The top test is from 2 days ago in the morning. The one right below is yesterday mornings test (looks negative). The bottom picture was from tonight. I’m so confused. The one from yesterday looked negative and the one from tonight looks positive. It doesn’t make since. My period is supposed to start any day. Do y’all think I’m pregnant or could be a possible chemical? Thanks!
