Miscarriage

My doctor just called me because I had some blood work done yesterday, and she told me that I had a miscarriage. I was only a few weeks(3) so my question to you ladies is how long did you wait to start trying again? I’m disappointed but I’m not gonna let it bring me down because at least I know now that we can get pregnant. I was just hoping this little bean was going to stick. When I found out last Saturday that I was pregnant I did have bleeding from last Saturday up until the day before yesterday. Any advice would help.
