Still no AF

Jessica
I normally have a 35 day cycle, the last two months were spot on for when AF started. Based on that, AF should have started on April 8. We only BD on the day I got an LH surge. Glow told me to do a pregnancy test 2 days shy of 2 weeks so I did and it was negative. I've had no symptoms and not sure if I should test again? Oh also, every day of fertile week I had spotting.
