Hello. I have a luteal phase of 10 days. When I was TTC#1 I took 50mg Vitamin B6 as part of B Complex Vitamin every day to try and lengthen my LP. On my second cycle I got pregnant. I then freaked out that the vits would give my baby a birth defect, but if I stopped taking them too soon, it would mess up my hormones and I'd have a MC. In the end I did stop taking them quite early on and ended up having a perfectly healthy baby. I am now on cycle 3 of TTC #2. I am not taking B vitamins this time due to the stress I caused myself with self medicating last time! As I fell pg so quickly, I always wondered if it was just a coincidence anyway. If not successful this month I will start to consider it again. So my questions are - has anyone else supplemented with B vits for same problem? Did you have success and do you know if it's OK to continue to take them during pregnancy? I can't find an answer anywhere?! Thanks
