had been on micronor before and was fine,took a 4 month break,back on micronor, after 2 weeks suffered constant nausea and bleeding/spootting cramps.i decided to come off it but a week later i am still suffering from nausea and wind,burping although spotting has stopped.don t feel sick in the morning when i wake up but throughout the day. been taking zantac which helps a bit.is it the pill just wearing off or caused stomach trouble or likely to be something else?
