I am 16 years old, I got put on the cerazette pill at the end of February 2022. I have had 0 issues with the pill until recently. I havnt had my period in almost 7 months. Last week I started to get bad period cramps but no signs of my period even though I'm not meant to get it whilst being on the pill. It's been 5 days since I've been getting something that looks like old/new period blood (brown blood/tissue) at first it wasn't enough for any sanitary products but for the past two days I've been needing to use them, I've never had experienced such bad period cramps up until now. Do I need to get in contact with my gp? Is it something to be concerned about? Did it go away for anybody naturally who has experienced the same as I am? And how long did it take for it to go away? I'm worried and panicking it could be something serious and I can't get an appointment with my gp until the 20th of September as it's not open on weekends and closed on the 19th for the queens funeral. Any advice ? Thank you.
