HELP!!! SOS!!!

Okay so my last period was 4 days late but came on the 5th (beginning of July) day and was kinda of light. I took a test and it was negative but then I got really crazy cravings for Chinese food this week and my dog is now sleeping right up under me and i have slight cramps in my lower belly. And really gassy. What should I do?!?!?!?!!??!! I had a miscarriage May 4th. I started my period the end of May leading into the beginning of June (it was normal)
