I’m not ovulating☹️

I took my period when I was 11 and every month up until I was 20 I took a period every 4 weeks. One month my period never arrived and it never did for 4 months.

Ever since then I could go 7-8 weeks without a period, sometimes even up to 3 months. I went on the pill in January 2022 and came off it in may as we decided to start trying for a baby. I took a period 2 weeks after coming off the pill and got pregnant in June but it sadly ended in a chemical. Since then I’ve been taking a 4-5 week cycle but this month I’m on CD29 and no sign of ovulation. I got bloods done to test my hormone levels, FSH, LH, thyroid etc and my thyroid is low, therefore I’m on medication. Everything else was perfectly normal.

Can anyone recommend any supplements I can take to regulate my cycles? It’s so disheartening not ovulating on time and never know when I’m going to take a period.
