12DPO with a bfp , what do i do now?

Im 12dpo today and i got my bfp last night , im very early i know hut i just want to know what steps i should start to take now . Should i go into a clinic and get tested for pregnancy as well or should i wait another week? What should i do to start preparing my body for this pregnancy? So far i have no super crazy symptoms . Im peeing a little more than normal, my body just feels exhausted and i have random cramp spurts that last for like 5 mins then disappear. Since i found out so early , i just dont know what to do to assist this pregnancy . Please help
