HELP PLEASE!

Aubrey

so I had my last period August 27th that lasted 3 days and I was feeling off beg. September so I took a test Monday September 10th and it’s said PREGNANT it was a digital, since I have took about 100 more all a BFN! Expected I think I may have had one faint positive on September 17th but since nothing according to the app my period is 3 days late. No sign of it. I’ve been super lazy most days, cramping on my right side often and left side sometimes, craving cheesecake and I don’t even like cheesecake. Could I have had a false positive? And maybe now I’m pregnant? Any insight would help I’m confused
