Early pregnancy symptom ??

I've been reading a lot of forums where women claim to have had cold like symptoms right before BFP. I'm curious to know if anyone else has experienced this. I never thought of this being a possible symptom. My period is due in a couple of days and I have this cold that sometimes feels mild and other times I feel like I'm dying. I keep telling myself I'm probably sick from going outside with my hair wet on a cold day. But either way I found this possible symptom interesting and wanted to know if anyone else out there had gone through this. I've also been having dizzy spells which I don't normally have- so much so I even fell this week from one.
