Hoping its a positive

Well, i am waiting to see if i miss my period & soo. I will buy a pregnancy test. But lately my breasts have been feeling different. Swollen/tender & near the nipple area it really hurts.. Is that telling me im pregnant because i haven't had that feeling as a woman in pregnant.. My fiancé has a feeling i am.. My areola area seems darker , but to me it does and at times it doesn't.. I haven't noticed the blue veins..  A little advice on what u experienced please.. Thanks
