Confused looking for some help

Shannon

I have had the coil for nearly a year now, and I haven’t bled until start of august and it’s been nonstop heavy some days then light lately and I have been in agony with the cramping, I have loads of pregnancy symptoms and took a test end of august and I thought I seen a faint line but told myself I couldn’t be pregnant because I have the coil in but took a test tonight and it’s negative so I don’t know what is going on can’t get a doctors appointment as they are fully booked, so just wondering if anyone on here has had the same issues with the coil
