Trying for baby #2...

So I was on the birth control shot for just over a year. And I've been off since September. My last shot was in June but it tore out in September...my husband and I are trying for another baby and have been trying since the end of February and its not happening so far. I'm getting really frustrated since literally everyone I know is having babies or finding out their pregnant and I'm not sure what else I can do to try to hurry this process along. My last period was the beginning of March and was only 4 days long. But then the next week I spotted for a few days. I've taken about 10 pregnancy tests in the last couple months and still nothing. Any suggestions???
