Jasmine

I’m currently 2 days late for AF and 16 DPO according to the app. 10 days after ovulation I had spotting for a few hours on the 20th took a test BFN and another test on the 22nd BFN also today took two more test BFN today. No symptoms other then my missed period and the spotting. Btw I had a miscarriage in Oct 2017 TTC since Feb 2018.. anyone know what’s going on or going through the same. I’m I testing early?
