Had a miscarriage at 6 weeks. already had one period cycle. obgyn says wait 3 months to try again. do i have to?

If you want healthy: pregnancy, you should wait 3-6 months after a miscarriage before trying to conceive again. It is important to allow your body to fully recover prior to getting pregnant again. Getting pregnant too soon after a miscarriage increases your risk of having another miscarriage. Repeated miscarriages in close succession could affect your ability to carry a pregnancy to term.
