Can vitamin B complex delay period?

its as the title says really? I've been reading up on how taking vitamin B complex is supposed to help when ttc especially Vit b6.. I only started taking them a few days before my expected ovulation date this month. i got them from Tesco theres only 1.4mg of b6 so wondering If that tiny amount can delay periods?

Af was suppose to come yesterday according to my app but nothing as of yet? I dont "feel" pregnant havent had any pms symptoms either had a few on an off cramps last week thinking Af must be on her way but nothing since...

Any advice would be appreciated
