Late !!!

LaShon • TTC BABY #2☺... ❤️❤️Goodluck & Baby Dust to everybody✨❤️❤️
So I'm on cycle day 35 & still getting bfn's... I'm always on time with my cycles... Always a 28 day cycle each month but I'm 7 says late & still got a BFN this morning... Anybody know why?!? Any advice or suggestions would help. Went to the doctor today & will start proveren (if that's how its spelled) in two wks if no sign of AF!
