Sorry again

I know I ask a lot of questions but i don't have a lot of people I can ask about these things .  My last period period was 3/28. I had a misscarriage in early May .  Haven't had a period since . My mom and fiancé think I should go back to the OB and see why I haven't .  I'm not pregnant again as I'm getting negative urine tests . Any ideas or opinions ?
