Need advice

Sarah • 22

Before you tell me to just go to a doctor i have already called my doctor and am trying to get in (i have free healthcare so it’s difficult to get an appointment). I have been stuck in bed all day because when i stand up i get a sharp stabbing pain in my head (think really bad migraine that happens in seconds). I am anemic, and i recently got the implant and have been bleeding for 13 weeks straight. I am just wondering if any of you have experienced anything like this or if you think it could be related? I suffered from chronic migraines for years so I’m not sure if they’re just back for me or if it’s something more serious.
