Baby Maybe?

Hello ladies! According to Glow in 5 DPO. We've been ttc for 5 months and been using preseed for 2 months. I'm feeling very nauseous and a lot of things are upsetting my stomach, my breasts are so sore, some things are smelling weird but taste the way they should and I'm just feeling really "off." I'm not getting my hopes up because my January period came 4 days early and my February period came 4 days late. But I'm really wondering if this could be the month. Any advice or ideas? Nothing mean please! Thanks!
