confused

So I what I think is a late miscarriage at 25/26 weeks. My little boy was so very wanted and expected. We buried him June 19 Father's Day.next baby was miscarried dec 23 of the same year. I said no more I've had enough heart ache. I have a cyst on my ovaries and I read it can give similar symptoms to pregnancy. So yesterday I took this clear blue test being I've been experincing pain but also sore breast and nausea. Is it the cyst causing the test to be positive it turn plus way to fast and I tested two days earlier. I can't feel happy I don't believe it, any thoughts?
