Pregnant?

I’m worried that I may be pregnant, I had unprotected sex Sunday night and now I’ve been spotting a little bit, my period is also supposed to be here in a couple days so hopefully that’s why I’m spotting. My breasts do feel a little weird but that might also be because I should be starting my period soon. I was thinking of taking a pregnancy if I’m late so that the test would be pretty accurate. Let’s keep our fingers crossed because I am not ready to be pregnant yet!!!!
