Help Please!

Okay ladies, I need some help. So I stopped my birth control on the 15th of May (last pill taken on the 14th). My boyfriend and I had decided that we were ready to TTC for #2. We had sex 6 times last month, I was supposed to start my period on Wednesday June 3rd, I couldn’t stop thinking about the test sitting in the closet so I took one that night probably around 8:30 or 9 and it came back negative. Today is the 7th and I still haven’t started my period... So I guess my question is, do you think it is from stopping my BC mid pack (took 5 pills of a new pack) or I’m pregnant? I’ve had the cramping I usually get with periods, but nothing else.
