Breast pain

So

OKay so I’ve been TTC since May 23rd, had sex on May 26th and basically every day since then. I’ve been having shooting or aching pains on and off in one boob all day today. I had pain like this but in both breasts right before I found out I was pregnant with my son. Could this mean I’m pregnant or something else?

Btw I was taking BC pills and I stopped taking them May 23rd too, if that matters
