symptoms of period vs pregnancy

I ovulated several days later this month than what my app suggested, however my AF has been spot on previously by the app's predictions. We've been TTC and used pre-seed this month and opk's to pinpoint our best chance.

I've had cramping and at times intermittent breast pain since ovulation and my AF is suggested to be due in 2 days. So essentially I've had premenstrual/ovulation symptoms for near 2 weaks. Has anyone else experienced this? (normally I had premenstrual pain a few days prior but no more)
