Can taking Flaxseed cause your menstrual cycle to be late?

I have been taking flaxseed for around 2 months now and I am now around 3-4 weeks late for my period. I take around 2 tablespoons a day instead of building up to 2 tablespoons so I think I may be overdosing. I am 15 and have had my period for around 3 years. I know for a fact I'm not pregnant for I have never been ually active. Thank you in advance :)
