Nosebleeds and headaches

Hi! 
My names Elleisha, this is my 2nd pregnancy and I'm 15w 5d.
Anybody else experiencing crappy headaches with nosebleeds? 
I've started having nosebleeds with headaches that then leave me absolutely drained, pale and odd.
:( didn't have this with my first although I did suffer from high blood pressure.
I've read that these are symptoms of high blood pressure, is it possible to have complications early on in pregnancy? I didn't have these till 26 weeks with my first.
Thanks x
