Hello Moms and Moms to Be!

I’m so frustrated with my bbt chart and was hoping for some clarity. This is my first time temping. I have mild PCOS (as I still get my period every month) I was put on Metformin to control it and this is my 3rd cycle on Letrozole (up’d to 7.5mg this cycle). I took a test on 10 DPO and 12 DPO and both negative 😩 Im so scared tomorrows test is going to be negative. Any thoughts based on my chart? Any BFP with similar charts?
