7w5d heavy cramping

I posted the other day about my cramping and everyone said it was normal. It definitely hasn't stopped. I took some Tylenol yesterday morning so I could make it though the work day, however they are still strong and fairly consistent. A lot of pressure on my cervix, more than uterine cramping. This morning I had a slight tint of pink on the TP. Should I call the doctor or see how it plays out today? This is my first baby and I'm kind of freaking out!
