Tina i have read the same thing many times!!!whau days are you taking the clomid again??? You might need it earlier days for earlier ovulation.... If you recall i took my clomid cd2-6, got o pain cd18 and a pos opk cd19, well i think i ovulated later because of the two days of soy i took, but it was still right under 21 days.... This cycle i am just taking the clomid cd2-6 and mayve ill ovulate two days earlier without the soy. They say that the quality of the egg after like cd22 is no good to implant... And the luteal phase... It think tweleve is kind of short, but i am not sure...it takes and embryo 6-12dpo to implant...but i am thinkinking if your embr. Tries to implant the same day or right at af its no good...but i am not 100% sure///i have read alot of conflicting things about it, but thats why i take progestrone cream after i ovulate, i am too trying to lengthen my luteal phase... They say women with pcos have low progestrone... Needed during the luteal phase...i am on cd30 still no sign of af, but like i said i am still on the cream...
