Pregnant?

April 4th I had a miscarriage at 8w3d. I bleed from April 3rd-May 14th and then started bleeding again May 16th-May 19th and what I assume was my period? I haven’t bleed since and my projected period was to start June 13th. I still haven’t started and have been extremely tired. We have been trying to conceive again. I can’t take my ovulation because every brand of ovulation tests I try say positive every single day of the month every time. I took a test today and it says negative and I would be 4w5d if I was pregnant. Is it possible to get a false negative that far along?
