Boobs are sore!

Alicia
4 days late and my boobs are so sore. More sore than ever and feel just uncomfortable and heavy. I had cramping yesterday for about 10 mins and today I found myself eating a yogurt then right after a yogurt I ate a pickle. Am I just tripping or could I be prego????? My boyfriend and I have been having unprotected sex but haven't gotten pregnant in 8 years. Could it finally be possible? A little worried as I had almost 6 beers last weekend. Comments welcome
