Question about B100 complex and LP issues???

[inpghttc]

Hello ladies, I posted this yesterday in the TTC#1 thread and didn't get any responses so I thought I'd try here. AF got me yesterday and so I am now officially starting my 5th cycle TTC. I am a little concerned about my LP and was hoping I could get some advice from those of you who also have these issues. If you look at my cycle only from with af officially starts, I have a nice long 14 day LP and a cycle that is every month exactly the same, even with ovulation....however, since I have come off the pill and started to TTC, (these past 4 cycles), I have started spotting lightly off and on from 10 DPO until af comes. Ugh! I am not sure if this will cause me issues with getting pregnant or not. I had a gyne appointment last week and she didn't seem overly concerned about it but she referred me to an RE that I can't get an appointment with until November. So, I am looking into some natural remedies that I can maybe try this cycle until I see the RE next month that won't hurt me if progesterone is not the issue. I am already on a really good prescription strength Prenatal that already has all the B vitamins in it, but was wondering if I should maybe try taking B100 complex in addition to it to maybe help stop the spotting. I am afraid of getting too much of the B vitamins as well. Anyone have any advice or other remidies?? Anyone spot like this and was able to get pregnant anyway?
