Please comment on my bbt chart

Tricia

Hello everyone, I have only started charting on glow this cycle but I’m trying to become pregnant for over 18 months with no positive results. Can someone have a look at my chart and let me know if I’m ovulating. I do have a regular cycle between 28 to 30 days. I took a first response pregnancy test with my first morning urine this morning and it was negative. Any suggestions as to what I should do next?
