Pcos , pregnancy and ovarian pain

Hi, I was diagnosed with pcos after many years of infertility, it was diagnosed whilst trying ivf to conceive, my menstrual cycle was usually between 30 - 38 days, painful and very heavy menstrual bleeding as well as mid cycle bleeding for aporox 2 days, after 10 years of infertility and no successes with the ivf clinic, my doctor put me on the pill and said to give my body a break which I gladly did, for the first time had regular periods no pain and lighter periods, after four months I ran out so stopped and the next month I was pregnant amazingly, after my daughter was born my cycles were very irregular again up to 48 days, I started exercising and lost a little weight which made my periods regular but much shorter usually 23 - 26 day cycle no mid cycle bleeding but have started having heavy bleeding again and am noticing ovarian pain mid cycle like an achy feeling right side which can last 5 or so days and also again just before my period, is this achy ovarian pain normal or something that should be checked out.
Any advice would be greatly appreciated.
Thank you
