Mildly high prolactin levels. I take it?

My obgyn prescribed me cabergoline (0.25 mg once a week for 4 weeks) to lower my prolactin levels, but I'm not sure if I should take it or if my prolactin level is high enough to take it. Please advise. I am a 27 year old woman. (163.5 cm 49.2 kg). Recently, I took a hormone test (on the morning of Day 3 of my period after breakfast). It seems I have high AMH and slightly high prolactin levels. My AMH level is 14.28 ng/mL and prolactin level is 33.97 ng/mL. The other hormones are: E2 68.48 pg/mL FSH 8.29 mIU/mL LH 9.29 mIU/mL Testosterone Below 0.49 ng/mL Free T4 0.79 ng/dL TSH 3.31 uIU/mL I have never taken pills or other birth control. I went to obgyn, but my doctor doesn't think I have PCOS because ultrasound didn't show cysts and I have quite regular period that comes around 33-37 days, lasting 6 days. But the doctor prescribed me with cabergoline to be taken 0.25 mg once a week for 4 weeks to lower prolactin. Is the cabergoline safe and should I take it?
