could I be pregnant?

Jessica
Help! So my period came a day early this month and day 1 of it was usual but the remainder of the days were spotting light and brown? I also had very light cramping and was very light headed and tired 😴 and I still am very tired.  And nausea..This has never happened before. Could I be pregnant? I'm 50/50 about taking a test bc I'm nervous about a BFN ... 😞😬
