My cycle is 25-27 says and my luteal phase is 10-13 days, can i try vitamin b6? ttc for 7 months.

You can : You can take vitamin b 6 but that is not going to impact your ability to conceive. Have you used a home ovulation kit? If you try for 12 months without success you should schedule a visit for testing.

Why?: I am not sure vitamin b6 will do much to help you get pregnant. The definition of infertility is > than one year of unprotected intercourse. Give it a few more months and if not successful, you may consider seeing your gyn or an infertility specialist. Good luck.
