So confused!

I’m so confused. On dec 22 I got 2 positive tests, they were blue dye so I retested that night with a frer, came out negative tested again in the morning with fmu on a frer, still negative. Went to the ER & they did blood it was negative but told me it might be too early cause I wasn’t due for my period until dec 25 and sent me home with prenatals. I tested again yesterday 12/28 cause still no period, slight nausea off and on and sore breasts, got a positive, but faint. Took another one that night, again very faint. Then took another today & it was negative. I am SO confused am I pregnant or not?! I know none of y’all are doctors but help a girl out my insurance with work doesn’t start till Jan 6 😩😭
