Early Pregnancy Symptoms

For the past few months my period date has changed from either the 8th or 11th, but this month I have yet to receive a period.
I've experienced a few things about my body that are different & I'm not sure if it is a sign of pregnancy. For example, my boobs have gotten so sore and tender it's ridiculous. Normally when I would get my period it would be that way for a day or two before...but this has been happening for a constant week and a half 🙊🙄
I don't feel extremely bloated, but I do look like I have put on some weight. No nausea, but sometimes I am more tired than usual. Not everyday. 
What were some of your early pregnancy signs? Just looking for some similar incidents 🙄
