Hi, Im sorry for your loss. I also lost my baby at 16 weeks, they told me it was dead at 14 weeks. I had DC , and I suppose you had the same. After that I waited 3 month. Doctor told me to have 5 time sex per week, so to increse the chanses of getting preg. After 3 month of trying I got pregn but unfortunately I have an empty sac, so I miscarry again. Dont lose hope.God luck.
The best thing to do is to chart your ovulation. I have never done this, after all of my miscarriages I have waited 3 months, and have never had an issue getting pregnant (just staying pregnant). I like the idea of waiting for the simple fact I was more prepared after the loss and my body was too. But unless you track ovulation you wont know when the best time to try is. Good luck.
