I recently had a misscarige at 7 weeks, I'm beyond devastated, was just wondering if this could affect future pregnancy? It was my first pregnancy

Sorry. Sorry for your loss. The miscarriage rate in humans is higher than most expect at approx. 25% or 1 in 4 pregnancies. A miscarriage this pregnancy does not mean you will have a miscarriage during your next pregnancy. In fact, chances are that you will not have miscarriage next pregnancy.
