Confused? 🤨🧐🤔🤷🏼‍♀️

So I haven’t taken a pregnancy test yet. But I feel a lot of symptoms, for example my nipples hurt so much and are so sensitive I can’t even have anything close to them. Also around my breast lots of veins pop out so in conclusion my breast are super tender. I been so dizzy and very tired as well. Yesterday my husband was eating a sandwich and I couldn’t stand being next to him the smell was just awful. I got off work and wanted some tacos and when I got in my car the smell just drove me insane I was so noxious and I love tacos I would never turn one down. I have already two kids but it’s been so long since I been pregnant that i am not sure if I’m PMSing or there might be a bun in the oven? I haven’t taken a test yet because I’m still one week away from my period so I want to wait until the day and see if I miss my period. What should I do? Can I even take a test now ? Is it too early?
