No PMS symptoms

Deedra
I do realize taking a pregnancy test is the only way of knowing, but I find it super strange that I have no PMS symptoms and AF is due in two -three days (my cycle is temperamental, usually 29-31 days) today is cycle day 28. I usually have extremely sore boobs, nausea, cramping around day 26 up until AF shows but this month there's nothing? This is the weirdest thing to me cause I've read PMS symptoms and early pregnancies symptoms are so similar??? Anyone have some insight or thoughts?
