Hello.. This is a really gross question but... Here it goes... I had a doctors appointment for birthcontol pills.. I have been on loestrin.. For two years a form of birth control.. When my doctor set up the appointment he accedently put it too far out so I wasent able to jeep consent with my birth control.. I was off for a week.. I then took it again and a period was skipped.. When I finally had my period.. It was very painful.. I blacked out and I couldn t breath.. When the pain subsided I had a huge peicw of jelly like skin substance come out of Me I would say it was half the size of my hand.. Yea I am sexually active since I am married.. Is this a muss carriage or a very bad period.. If so then what was this that happened too me sorry for the gross story but I need to know.. This is day 6 and I m still on my period and still haveing a lot of pain.. With birth control it usually only last 4 days thank you
