TTC for the past 1 yr

Pink
Hello ladies, am 27 and before 1 year I got pregnant and had a D&C when I was 2 months bcos of the blighted ovum . 3 months after surgery we were back on TTC mode from jan 2015 but till now nothing turns positive. We checked with doctor, she advised me to try for 1 yr but after every AF I am so much depressed. Any tips ??
