I originally had a labrascopic diagnostic surgery done back in 2015 because my period cramps were so bad that I would pass out from the pain and I would bleed so much. Well here I am about a year after the diagnostic, that came back with "nothing is wrong with you" and I don't bleed anymore. I am on birth control but my cramps are still unbearable and I still get sick on my period. I bled at first but I began to notice the lack of bleeding around April of this year (2016 as I write this) but now at September I haven't seen blood SINCE April. I am supposed to see my gynecologist for a post-op check up but they're low key refusing to see me. I just want to know if I should be concerned because I am really scared. I mean, a period is meant for all of the waste and tissue to be expelled and now nothing is being expelled, can't that be dangerous??? Please some advice???
