I haven't experienced a loss before, but I know many on this board have abs I've heard people talk about their OBGYN telling them to wait before trying again.....looks like that is an outdated practice (obviously if there are complications follow medical advice!).
this study clearly states there is no medical need to "rest" your body after a 1st trimester loss.

As far as ovulating while HCG is still above 5, it's highly unlikely. Levels above 5 tell your body that you are pregnant, you body is made to NOT ovulate when you are pregnant. I'm sure there are rare exceptions, but it's very unlikely.
"Limited, flawed evidence underlies the recommendation that couples wait ≥3 months after an early pregnancy loss (i.e., <20 weeks' gestation) before attempting to conceive again. In a secondary analysis of a trial of preconception aspirin use among women with histories of pregnancy loss, investigators capitalized on the availability of self-reported data about timing of pregnancy attempts (not just the actual pregnancy events). Birth outcomes were stratified according to whether subsequent pregnancy was attempted within 3 months or longer than 3 months after early pregnancy loss or termination.
Of 1083 women, 77% attempted another pregnancy within 3 months of an early loss. Compared with women who waited longer, those who started trying to conceive within the first 3 months were more likely to achieve pregnancy that resulted in live birth (53% vs. 36%). Median time to pregnancy was shorter for those who started trying earlier (5 months vs. 6 months).
Comment
High-quality data are accumulating to refute old recommendations to wait at least 3 months after an early pregnancy loss before trying to conceive again. In this era of patient-centered care, we should share these data with women who have experienced a pregnancy loss, many of whom are eager to attempt conception as soon as is “safe.” While reproductive life planning should take into account emotional and financial preparation, we must stop misinforming women that their bodies are physically unready for another pregnancy soon after a first-trimester loss."

This isn't my specialty area, but I do see women with pregnancy complications and early loss often (L&D won't usually see women until they are past 24 weeks).
