Is it too soon???

Hey y'all! I'm supposed to start my period in 5 days, but I'm concerned. For the past 2 days my nipples have been so tender, even putting on a bra is painful. (Though not wearing one hurts more when get bumped) I've been exhausted for about 3 days now, no matter how much sleep I've gotten. Then again, also getting over a bug my boyfriend gave me, so that could be cause for being tired. Just feeling BLAH in general.

I normally don't have tender nips like this, especially 5 days before my monthly arrives! Or tiredness this far in advance either....

Do y'all think I'm worrying too much, or could I be showing pregnancy signs this early??
