When I went to my RE with that concern she said that technically it can be as low as 8 days and you still have a chance. My luteal phase ranged from 10-12 days and this is pergnancy #4, so I think you will be okay! I got my BFP at 8dpo, so that is proof!
Can i get pregnant on days other than my ovulation day
10 days is a little short for Luteal Phase. That does not mean that you can't get pregnant. I would make sure to check Progesterone levels because low progesterone levels can cause a miscarriage. You want to try to strengthen your Luteal phase a little. Have you spoken to the doctor about this? I recommend you do so soon... A lot of people get pregnant with a short luteal phase but you still want to make sure there is nothing off KWIM? Good luck to you..
