just wondering if you could give me some advice, Im currently 9 days late for my cycle. And since having my daughter over 13 months ago I have being very regular could I be pregnant?

I have hypothyroidism but is controlled by medication and I'm also overweighting. I'm not actively TTC but if it happens it happens.

Attached is my cycle chart. Can anyone also tell me whether it is regular or not it's since I got my first cycle after having my daughter last year
