How sore is sore????

Hi guys,
Ok so my boobs are really killing me, even when I walk fast or drive over a speed bump they hurt!!
My AF is very irregular, sometimes it is around 31 days, then 43 and last month it was 40 days. Today I am 34 days and my boobs have been sore for over a week now. I do normally get slightly tender breasts at that time of month but these seems much worse.
I am going crazy wondering if this could be something or not! I don't really want to take a test just yet because in the past my AF had ended up showing her ugly face!
Has anyone else had sore breasts like this and ended up being pregnant?

Yes. But I have also had sore boobs like that and not been pregnant.

Yes, but I wouldnt be going by that only.. My boobs seem to be the least of my problems when pregnant.
