I was 11 (but a month off turning 12) and at a residential summer camp. I had no idea whatsoever and wanted an ambulance, I was hysterical until the group leader, explained to me in broken English it meant I was a woman but I wasn't having a baby at the minute. lol
When I was around 26 my periods stopped fully for over 2 years, it is now put down to medication that I was on long-term as next period came about 6 months after I came off the med concerned.
About a month later I had a bleed which started very suddenly and violently, I had gone out for a walk but only managed 20 meters when it started as no pain, over the next 6 hours, I lost just over 4 pints till they got the bleeding stopped.
I lived less than half a mile from hospital but I called an ambulance as the blood was dripping out of me, they told me to leave door on latch and just as well as when they came in, I was passed out in what looked like a murder scene, they looked around the house at the scene and asked several times could i be miscarrying, no as I knew I wasn't pregnant, i barely recall leaving house then and next thing I was in a&e resus with a load of staff around me.
Also was diagnosed at the time with endometriosis as they saw it while doing repairs and testing and other fix-ups however I cant have hormone-based treatments as such anymore.
Another gynae consultant did allow me to try chemical menopause with HRT as I'm now 42 and periods have as much left me as while I had a couple of months of an injection and the side effects were too dangerous,
In the past year I have had 1 period it lasted 2 days (started night, finished by next night),
in 2016 before chemical injections, I had a total of 2 in around the same duration,
in 2015 I think I had 3/4 but I know there was definitely one around Nov 15 which was a really long and painful one for me as it lasted over 2 weeks, i remember it distinctly as I was in respite care as a step down bed from a hospital admission so was dependant on help from care staff in the unit who commented about it as they were doing their record keeping
