Is there still hope?

I BD on the 30th but I’m not sure if I was ovulating. All tests have been negative including LH tests. I started testing my levels on the 3rd but they just faded away as the days went by. Is it still too soon could I just have really low HCG levels to tell right now? My periods are irregular so idk if I missed my period or not…should I just wait a few more weeks?
