Any BFP stories today?

So I've been ttc for like 2 mnths now got off birth control in july..and had on ovulating days that month and this month..I took like 3 a test earlier this month all came out negative..but ever since then i've been having mild cramping off and on...so for some reason I took one today and it was positive :) ...so I ran back to the store and grab 2 more but those were negative :( so wat do u think is going on..I jus have this feeling that I had a false positive cos all the others were negative
