cycle tells me one thing test say another

Viviana • No judgment please ! Yes I am young . I`ve been trying to conceive for two years and 6 months no bfp yet .
My periods have always been regular or sometimes just a day earlier . I've been trying to concieve for two years and six months .My period is 15 days late . All negative and I've taken on a wide range apart. My doctor didn't want to give me a blood test because " it would of been positive on a pee test tomorrow " I finally was given answers after going to a clinic and I was told my period was late because the pervious month I lost ten lbs . Tomrrow is 12 days since I've last had sex . Is it too early for a pee test ? It's really discouraging not knowing what's going on . Also I've been having crazy discharge . From sticky , thin , thick and creamy . Just need some answers 😪 all I want for the holidays is a bfp It's hard to explain but I do have a feeling I am pregnant like it doesn't make sense to me late period and negative test . But yet I've been craving things , sleeping a lot more , having painful back pain . Any miracle stories ? Also kinda scared to ask for a blood test because my doctor turn it down .
