Married mommies and married mommies to be?

My husband and I have been married for 3 years. We had never used contraceptives but weren't trying to get pregnant either. Honestly, from past relationships, etc I did not think I could get pregnant. I'm not sure if this is the reason we got pregnant or not but he started taking this stuff called bee pollen. It is all natural bee pollen granuals. He was taking it because someone told him it would give him energy. We found it at the local farmers market. A couple of months after he started taking it I popped up pregnant. I am 30 weeks along now. We did not do anything different than before other than the bee pollen.
