Pregnancy or PMS?

I started having cramps a week and a half after AF. I have experienced cramps every day since. I'm on day 24 of a 30 day cycle. Since I noticed the cramps I have also experienced 2 days of sore breasts, headaches, moodiness, an increase in urine (I pee a lot anyways) and lately I've had a lot of heartburn and gas. AF is not due for another week. TTC first child so I don't know exactly what I'm looking for with pregnancy symptoms.
