Scared- 9+ Days of Cramping...😨

Sarah
I don't want to assume pregnancy, so let's start with Ovulation pains...
I read that Ov. pains continuing more than 3-4 days should seek medical advice.
I also read that ongoing cramping could be a sign of the uterus stretching etc readying for baby.
I have had other pregnancy signs, so I'm hopeful but could use some advice please :) 
(PS a test on 7dpo and 9dpo were the expected BFNs)
