[|AI|]  Hi welcome to Chat Doctor. I have gone through your question. Sustain is progestin containing medicine. It will help in luteal phase in maturing endometrium and help fetus in implantation. So sustain is generally prescribed in later phase of cycle. Fertile days are +/-3 days to ovulation. If you have ovulation on 14 then 11 to 17 are fertile days. Hope I answered your question. Would be happy to help you further. Take care.
