Go or no ?

I'm 15 weeks and I'm having intense cramps on one side, the right side. And I've never had a nose bleed in my entire life and it's bled 2 times today for 45 minutes each time. I've been dizzy, and nauseas all day & have a bad bad headache. I haven't been to the doctor since 8 weeks. Should I go to the Er ? Or no?
