I missed my period on june but on july i started having a brown discharge for five days like if i'm was having my relugar period but no and i'm ttc?

Difficult to say: If you have normal cycles, you should be able to predict when your ovulation window for august will be. Typically fertility window is 9-14 days since beginning of period. So if period starts on first of month (i don't know your cycle, but let's pretend), then on day #9-14 of that month is your best window. You may want to get an ovulation tracker app. There are many to chose from!
