Sorry for your loss.
How far along were you? That will make a difference in how soon you can try again. I would suggest using ovulation predictors to help you plan out your next try. You can get them by the pregnancy tests at the pharmacy. It makes it so much easier when you know your 'window of opportunity'.
I experienced a loss last year. I was about 18 weeks pregnant. It was 5-6 weeks before I got a period again. I am currently 13 weeks pregnant, and I hope this one stays put. I told him he has to 'because mommy said so'
