Honestly I can’t tell, I get very crabby and my husband tells me to go take a test lol
My first sign was super sore breasts with both my pregnancies.
Sore boobs was my first hint with all five then came the pure exhaustion
Fatigue, sore/swollen breasts, increased hunger
Sore boobs which took weeks to go away!
Heart burn, bloating and sleeping less or more than usual.
Boobs hurt like bad… sick and smells bother you - fatigue
I would have to say, unprotected sex!
