3 days late

Connor

So on the 29th I had a blood test done and it was negative well 5 days later still no period. I have slight cramping on one side only and sore breasts and LOTS of cervical mucus. I ovulated last month on cycle day 15 (its cycle day 30) and had sex every day after my period this cycle I feel pregnant but I don’t think I’d still being getting negative test results if I was pregnant. Opinions?
