Pregnancy symptoms

My boobs will feel randomly a little sore before af but for the past 3 days(I'm 11dpo and trying to get pregnant, no positive test yet)they have been extremely sensitive and tender, especially around my nipples. I don't remember this with my first two kids but my youngest is 4 so it's been a minute for me. AF is due the 8th according to the app(af started December 10-11th last month)but should I read into my breasts being this tender as a pregnancy sign. I've been a bit emotional and peeing a lot too but I didn't think of those as being pregnancy related until yesterday. What were your first signs of being pregnant?
