pray I get my period ladies!

My period was supposed to come on the second but hasn't showed . I'm officially 2 days late ... no big deal I'm really not stressed out . But my boyfriend sort of is . We had unprotected sex recently and even though I really doubt I am , if I don't get my period by Thursday morning I'm taking a pregnancy test just to ease our minds . I really don't want to spend the money on that when I'm like 99% sure I'm not pregnant and my period is just late (as per usual) so pray I get it so I don't have to spend the money on a test and so I know I'm not pregnant ! I have been nauseas, having back pain , being tired and peeing a lot but I'm pretty sure that just has to do with me being sick with a cold and drinking a ton of fluids .
