Hi all

I'm so fearful that I'm being dramatic and fear I'd be wasting my GP's time

I'm 34, have no children, but feel I have symptoms for Ovarian Cancer 

I get bloated quite easily, I have what feels like niggly period cramps most days- they're not unbearable or anything but i know they're there, I have terrible lower back pain which ranges from bad to the point of being unable to sit/stand or lie still, I'm constantly feeling exhausted, mood swings, and my bowel movements change from being constipated to urgently needing to go, sometimes 3-4 times a day. These symptoms have been going on for almost a year. 
i had the copper coil fitted in February and put it down to that; with the back pain I've tried treatment. 
however, this weekend I've started bleeding- not heavy but spotting enough that i need to wear pantie liners- this is unusual for me. According to my calculations I'm mid cycle- i had a really bad 'ovary ache' yesterday and then started bleeding and have been consistently spotting since. 
i do have a stressful job and have been particularly stressed the last few weeks, but the bleeding hasn't happened before 

does anyone have any explanation? I'm worried I've done the classic of googling my symptoms and the worse has been revealed 

thanks and love to you all x
