Been getting crazy burst of emotions, crying!

Milhu ā€¢ 31yrs, DH 39... We have 2 girls, and working on our rainbow šŸŒˆ baby.. Currently pregnant and praying this is it!!!
I don't know what's wrong with me, maybe it's just AF trying to creep in but I prey it's a BFP!! I have really sore nipples, lower back pain, feel like I get sick to my stomach at times.. And some food cravings.. AF is due 11th thru 14th. Anyone else feeling any symptoms? Please share..
