when can I take a pregnancy test???

Emeline
I've had unprotected sex where my boyfriend finished in me (I'm on no form of birth control) three times since my last period which was 1/22- 1/27 the 31st, 5th, and 13th. My period according to glow's magic is due the 22nd. And ever since early febuary (I think after the 5th) I've had a feeling I was pregnant. I'm thirsty all the time. Insomnia has been kicking my ass but I've also been super tired which sucks. Headaches. Oh my god. I get migraines really really bad so these aren't like sending me to dark rooms for meds and eventually the hospital for fluids and an iv cocktail but this is annoying. Plus I've got the period brain which has me crying during every Valentine's Day movie which is weird and like wanting nothing but babies and affection. Also I take public busses and the smell is so getting to me and I've never noticed it before and I'm getting motion sickness which is just nausea but still annoying  and new so like I've got this gut feeling I've got a baby cooking but if not I should like go to a doctor probably. 
But long story short when should/ can I test I don't want to waste money on tests if they won't be accurate???
Also like I live off of rockstars and espresso half the week so knowing if I should cut back some (or entirely) would be smart.
