PCOS. NEW CYST OR PREGNANCY?

After being diagnosed with PCOS in October 2017, had a period in October, none in Nov. But I had a normal period this month. (Dec10-16) Periods usually last 3-5weeks😑😔 Two days later after my period went off, I have tolerable pain near my left ovary that comes and goes. I said well since I have PCOS, my period may be coming back on, but it has not returned, but the pain comes and goes near my left ovary. Should I take a test or just wait until my period shows up? Really want a child with my husband
