Sierra
I recently posted that myself and my ex had unprotected sex on the 8th of January . My period was due to come on the 16th obviously it's still not on if I'm writing about it .. Going on the second week now that my period is late and in the 40's for my cycle day . I don't want to tell him I don't even want to take a test I just want my period to come on
