Help I'm kinda confused !

I was hoping you could help me with a weird question.

It says the past two months I've had a 30 day cycle which means I was most fertile from the 21st through the 27th if I TTC on the 19th-23-26th "Glow say"

Im due for my perid the 9th, I took a test this evening and it was a negative, does that mean I am NOT

Also Just had my iud out in May, After 9years.

Please help?
