Weird period am i pregnant?

Lacee
So i stopped taking my birth control pills about a month ago after being on them two months well last month my period only lasted a couple days and i thought i was pg but tests said no this month when i got m y cycle i barely spotted the day before i was supposed to start then stopped then had a medium flow the next day which didnt even soak a full tampon and i was done bleeding except a tiny bit of spotting im tired of going to the doc and spening money on tests just to keep getting negative results. WHat do yall think
