Brown Discharge but no period!

Megha

Hi Ladies, can I check I ovulated on 16th May and my period supposed to come 30th May as per the app and still didnt show up. I am having mild cramps on and off. Will this discharge could be early pregnancy symptoms, should I test for pregnancy or this is sign of period coming. Because before my period starts I get the brown discharge but the cramps quite intense. Thanks for your advice.
