Pregnancy after miscarriage?

I just had a miscarriage earlier this week at 6 1/2 weeks pregnant and I was just curious if anyone has gotten pregnancy immediately following the mc, and gone on to have a healthy pregnancy?  Not that I'm trying now, but we are going on vacation in a few weeks and I want to be able to enjoy time with my husband without worrying that I may get pregnant too early and mc again.  Dr says to wait 3 months and I'm not totally against that but we've been abstaining for the last 3 weeks as we were concerned about the pregnancy.  Now I just want to enjoy life again without restriction, if you know what I mean 😊
