On Coil but feel like I’m pregnant

Chlo

Someone please help me out!!! So I’ve ha the coil now for around 6 months my youngest is only 9 months old I’ve just started to have loads of symptoms I had being pregnant with him such as mild cramping, headaches and sleeping through the day, never had this before whilst on the coil I also can’t find the strings to it, I thought I’d take a test yesterday morning checked on the evening and you could clearly see a very very faint line which my partner also agreed to but said there’s no way i could possibly be pregnant today I decided to do another to make sure it didn’t come back as faint as it was yesterday today I couldn’t see much but is this just my eyes or can anyone else see anything at all?? I’m so lost I’m not sure what to do next 😩🤷🏼‍♀️
