I don't know what to do

So my last period was about the end of May and I bleed for barely even a day at the end of June, some of my very close friends think I could be pregnant because I have always had very regular and heavy flows and I'm not gonna lie I'm very active with my boyfriend. I just want oppions I'm open to everything and I'm going to get a test on pay day because I just used all my money on bills.
