Trying to Get Pregnant

Prenatal Vitamins and B6

Good morning... quick question...is the B6 that's in the PNV enough to lengthen your LP without taking extra B6? I'm just curious because I started taking PNV a few months ago with we started TTC, and last cycle my cycle was longer than usual (it was like 34 days instead of 29). And this cycle I'm on CD 18 and still haven't O'ed yet. So my question is: could the B6 in the PNV be extending my cycles without taking any extra B6? I started temping this cycle so I have a better idea of what my body is doing...but just looking to see if this has happened to others. Thanks!!

Re: Prenatal Vitamins and B6

  • I don't know about the amount of B6 making your cycles longer, but 34 days really isn't outlandishly long. See what happens this cycle. 28 days is just an average, very few women actually have 28 day cycles.

  • I dont think there is enough B6 in the prenatals to lengthen your luteal phase - I'm pretty sure it needs to be about 50-100 mg but I wouldn't advise taking it without talking to your doctor b/c too much B6 can cause nerve damage if my memory is correct.

  • It would probably depend on how much B6 is in your Prenatal. Its pretty common for womens cycles to vary that much, even more.

  • Thanks...yes I wouldn't start taking extra B6 without consulting my doctor. I know the variation isn't that big but I have had 29 day cycles for the past 2 years about... so last cycle just threw me for a loop! Have a great day!

    Yeah, I understand..every time you think you've got your body all figured out, it will throw you for a loop to keep you on your toes!! Hope your day goes well also Smile

    This I take a PNV and a B6 pill-but I was warned you have to be very careful & check how much B6 your PNV has before selecting a B6 supplement. I haven't had a lot of luck with it increasing my LP-so I guess it depends on how your body reacts to the B6 (if it works or not). My dr is a skeptic on this one.  Sorry.

    All the bolded stuff above, plus I read somewhere recently that whether B6 will lengthen your LP depends on what the reason is for it being short. 

    So far it seems to have given me an extra day, but I also had 7DPO b/w today to see if I have a progesterone deficiency.
