How do I get short term health insurance in New York?

Hello, I need health insurance and having a hard time figuring out what my options are. Heres my timeline of events:

April 2024: I lived in California and was laid off from my job, lost my insurance. Signed up for Medi-cal. June 2024: Got a freelance job with enough income to disqualify me for Medi-cal. Became domestic partners with my partner and went on his insurance plan, cancelled Medi-cal. July 2024: My partner got a new job in NY, and we relocated. His new job insurance won’t kick in until Oct 2024. Lost my insurance again. I did not opt into his COBRA plan because it was too expensive. Oct 2024: I plan to register for domestic partnership in NY and get on my partner’s insurance with his new job.

What do I do from August 2024 (now) to October 2024? Do I qualify for any government plans (assuming no because of my freelance income)? If I sign up for state plan, can I cancel in 2 months? What are the open enrollment rules? Do I qualify for catastrophic coverage?

Any resources or advice would be greatly appreciated. Thanks!
