Sensitive or smelly?

May be TMI, but with my period due in two days I'm wondering if maybe it's an early pregnancy sign. We've been TTC. My weird symptom is I feel like I smell! I have more B.O than usual and I'm noticing it a lot. Last night I took a shower, and I smelled like B.O less than two hours later. Deodorant barely helps. No one else has mentioned it though. I googled but it doesn't say much. Anyone else experience this before a BFP
