... menstrual issues when they were on plaquenil ive been on this med. for 26 years and was off of it for 1yr 6months when i was trying to get pregnant and afterwards i breastfead my child but after that was back on it and now its been like 10 years no more period and so was thinking that it might be because im taking the plaquenil? Would like to see if i stop the med. would i get my period back?
