pregnant?

So I've been having symptoms for about 3 weeks, sore boobs, cramps, back pain and I've been extremly wet and have not been itchy so I know it's not an infection... only problem is I came on my period just over a week ago, I'm normally on for a full 7 days and never get cramps  however I was only on for 4 days and I was cramping like hell, I'm still experiencing the symptoms and took a test just before my period which came out inconclusive , could I be pregnant? I know I should do a test but was just wondering if this had happend to anyone else
