Mixed signals

Kellie
So, I've been crazy sensitive to smell (old food smell, well-food smells in general) among other symptoms for the past 2 weeks. 
I am about 4 days before my AF is supposed to start, but just started to get a sore armpit, which is one of my AF signals. 
My question is: do women experience some of the same symptoms, even if they are pregnant? My daughter is 3.5 now, and I don't remember from my first pregnancy. 
I'm trying to not psych myself out too much. Ugh. The WAITING!!!! 😩
