PCOS - I think I'm pregnant?!

Chloe • 2 angel babies 😇 😇 ❤️ 1 baby on the way 👶 💕
I'm 24, I miscarried at 17, no contraception since, been with the wrong people, now with the love of my life.
Never thought I'd conceive with PCOS - doctor said I'd need support/treatment to help as it hasn't in 7 years. 
Have had sore larger breasts, tummy ache.. thought I'd take a clear blue test. It says "pregnant 1-2".
Is that 1-2 weeks, or 1-2 weeks from conception.. if so, how far am I?!
