Help Please

I posted yesterday some very light pink spots on my bathroom tissue and  all day today I've been nauseated and just a moment ago, I actually threw up. My boobs are more tender than they've ever been but only at night and my back aches all day. I think I'm 7dpo but it's possible that I'm 8. I had a peak smiley on CD14 and the morning of CD15. A third test that night showed my LH had dropped. Could I be pregnant? I feel like 7-8dpo is way too early for these symptoms???​
