is this normal???

Pregnant with baby #4
I am cramping really bad. It's in my lower abdomen. Almost as if it's a period cramp maybe a little worse. I am also having a heavy white/mucousy discharge. Even though this will be my 5th pregnancy I have never had this symptom. So if this normal? I believe I am 4 - 5 weeks. Just got a positive test last Thursday.
