should I test or not?

Hey ladies I just had my period last week it ended on Friday. My husband and I went on vacation and of course we had sex unprotected and now my breast are really sore and when I was wiping yesterday it was pink on top of that I keep going to the bathroom to pee and I feel like my period is coming back on...I am so confused because I think it's too early to test I don't know what to do..can I get some opinions please?
