I am 10 weeks pregnant today and ive been getting cramping in my stomach, i wiped after using the bathroom and there was a brownish mucus in the paper and something little in the toilette, ever since ive been getting sharp pains in the right part of my back. Did i miscarry? I havent been for an untra sound yet and doctor made and appointment for me for when im 11 1/2 weeks for a pap but not yet an untra sound. Im calling him tomarrow and insisting on hearing if there is a heart beat. Im really worried, is what i experienced bad?
