I am really confused right now. My period is almost 2 weeks late, not having many symptoms other than having to pee all the time (no pain). Took a home urine test yesterday first in the morning and it was positive, took one later in the day yesterday, it was negative. Took another one first in the morning today and it was negative again. Had a blood test done yesterday but haven't got the results back. I'm ttc and I'm wondering what would cause a false positive, and why the other tests came up negative.
