So I don't know if anyone has experienced this or can help! I have cycle between 23-35 days but I have all the pregnancy signs etc. I've not been very well and I've had a large amount of blood in my urine( basically it's just blood no wee) I did a test and it showed positive for 2 mins and then disappeared and showed negative, this happened on both test?! Could this be because there so much blood in my urine?
