TTC after losing our baby

It's only been 4 months that we've been trying since we had to terminate pregnancy back in May of 2016. Every month my period comes, and I lose a little bit of hope each time. I have been talking to a friend who also lost their baby at about 12 or 13 weeks and they have been trying for 13 months to get pregnant again. I'm worried it's going to take us that long and would like some advice or tips on what you wonderful ladies think helps boost fertility.
