B6 Deficiency & Birth Control Pills

Today I was reading about the benefits of B6 in alleviating morning sickness. More specifically, the article discussed how women suffering from B6 deficiencies are more prone to suffer nausea during pregnancy. Interestingly enough, birth control pills are known for hindering the absorption of several nutrients - including B6, B12, and folic acid. I can't help but wonder if my body was slightly deprived of proper amounts of B6 (having conceived while still on the pill). Because I've been on the pill for almost 5 years now - there is a good chance this may have been the case. 

I began adding B6 supplements (100 mg of P-5-P ... the most active form of B6) into my daily regimen about 6 days ago. Interestingly enough, my nausea symptoms greatly improved about 4 days ago. While correlation does not equal causation (especially in this case, when so many factors are at play), it is interesting none-the-less.
