Non hormonal BC with PCOS

Jessica
Hi! Im 22 and on the pill after having my first child last year. I was TTC for 11 months while using BBT and didn't ovulate at all during that time. My husband and I split up a week before the birth, and I have met an amazing guy who I've been with for 6 months. We have talked about having kids in 2-3 years and when we first started dating I got the IUD however he could feel the string as he quite well endowed and it actually got to the stage where he would t want to have sex. I went back on the pill but it makes me feel nauseous and I hate the synthetic hormones. Does anyone have any ideas on what BC I can use aside from the pill (and not condoms or IUD)? I was thinking fertility tracking but I'm a bit unsure because of my PCOS. Thanks!
