QUESTION!!

So, I’m 5 DPO.

Today.. well Monday I started feeling extremely dizzy. And I know it can’t be my water in take because I drink a ton of water. But I was heavy crazy dizzy spells. And then my hubby was giving me a full body massage (which was AMAZING may I tell you 😍😍) and when he finished he had asked me if I started my period and I said no because I’m not due for at least another week... and I checked but it’s brown & not enough to be my period. What could it be?! 😫😫😫😫
