Hi, I'm new to all this and I'm going to lose the plot trying to figure out what's going on, bit of background, I have a mirena coil which reached it's 5yr change in may (I didn't find this out till mid may 🙈), I'm normally regular with my periods but my last one was on the 20/4/18 and I have missed my may period, I have spent a small fortune on pregnancy tests, clear blue and first response, clear blue all 4 negative (last one yesterday 2/6/18), first response all 4 positive (last one 1/6/18), but they weren't dark lines, they all appeared at the 3 minute mark, easy to see and didn't disappear but they still looked faint, which test should I trust??? I'd be roughly 6wks now so clear blue would have picked it up surely if I was? I can't see my doctor till the end of next week and I don't know what to make of these tests! any feedback would be greatly appreciated!
