Fat & Ovulating

I weigh 290-300 lbs and am 5’8. I am obese but my cycle is normal. I ovulate monthly (well since I started BBT in Jan 2020). My luteal phase is 12 days. My cycle is 25-27 days. I walk daily 2-3 miles & started to watch my portion size. Never had a dx of HTN, PCOS, ect.

Is this normal for someone my size? All I see is people my size having difficulty and not ovulating.

My husband wants to try for a child but I am scared due to my weight.
