Is Cramping, Breast Tenderness, Urinary Frequency, No Periods Due To A Pregnancy?

Hello, Okay well I'm wondering if I could be pregnant. I can't exactly remember last month when I got my period but, I'm pretty sure it was somewhere between the 19th and 25th. I know I've already ovulated because I've had the mucus like wetness. I've had sex several times during ovulation and after but my husband never did actually cum inside me. Two days ago I had cramping, so I thought I was going to get my period and it still has not come and I haven't had anymore cramping but I've had alot of wetness. I took a pregnancy test yesterday and it showed up negative. Getting to the point here, I'm having wetness, breast tenderness and urinating frequently and one day of cramping and so far no sign of a period. What does this mean? And even though my husband hasn't actually cum inside me could he still have gotten me pregnant?
