6 weeks and too beat

Me

So i am around 6 weeks pregnant but i feel super duper tired..like literally to the point where i cant even gather the energy to get out of bed. The mere thought of driving is killing me. My head aches terribly and i just wanna keep laying down . Has this happened with anybody else. I have 2 kids and i am 35 but never felt like this with my earlier pregnancies. I am so drained and fatigued with a heavy head.

Is this even normal ?

Please if you guys cud share ur experiences with me it might give me some hope.
