Are these symptoms?

I'm supposed to get my period in 4 days. Today I saw my bf for the first time in a week and he touches my boobs and goes, "they got bigger!" I'm like the hell you taking about, they the same size, boobs don't randomly do that. And he continues to grab them all day and go "they're bigger!" Recently too, I've been having very very vivid dreams, probably over the last week. I've heard this can be a symptom of pregnancy in some women. Am I overthinking this or do you think these are true symptoms? Can you also maybe include your experience with early pregnancy if you relate to these symptoms? Thanks so much
