Pregnant?

I have PCOS I don’t know when I ovulate but I had sex on the 9th and 10th of June and also the 17th as well . . I’ve been having VERY tender nipples , and I’m very moody . I’ve gotten 4 faint lines but I don’t know if it’s my PCOS or not . In y’all a opinion do you think I’m pregnant or do u think it’s my PCOS ?
