Since your prolactin has been normalized for more than six months but you still have very long menstrual cycles, I think this is the time to speak with your physician regarding other possible reasons for your oligoovulation (infrequent ovulation) such as thyroid problems or polycystic ovary syndrome (PCOS).
Njengoko i-prolactin yakho ikwimeko yesiqhelo iinyanga ezingaphaya kwezintandathu kodwa usenemijikelo yokuya exesheni emide kakhulu ndicinga ukuba lixesha lokokuba ubonane nogqirha wakho ngoku eli ukuze nibonisane ngezizathu ezinokubangela ukukhutshwa kwamaqanda avuthiweyo okunqaphazayo ezinjengeengxaki zetharoyidi okanye isifo sokuba namaqhuma kwisiyilelo-maqanda (PCOS).
