Do my chances sound good?

Haven't yet missed my period but I have extremely sore breasts and have done since 1dpo - they are literally so pianful! Even to put my arms down too hard or quick they ache and hurt super bad, I can even feel them with a bra in and usually I don't even notice my breasts are there, also early hours if this morning I couldn't get comfortable in bed as I had leg cramping and cramps in my arms and no matter what position I lay in, it wouldn't go! My legs just ached like someone had given me the old school dead leg! I've had the odd little but of light cramping here and there but not a lot, mainly just my breasts feel heavier and painful along with the cramping! Can't say I feel fatigued as I work practical long shifts at work were I am constantly on the go so I'm always shattered, but I have noticed myself crying easily and getting very snappy at DB. Do my chances of pregnancy   sound pretty high?
