One common symptom with my last two and this one is nausea. It was not bad and usually when I are a little something it subsided. That's how I knew something was up and usually pretty quick after conception. I would take a pg test just to confirm and show my husband. Usually I get in to see the doctor as soon as I find out. I am a firm believer in prenatal care.
Along with prenatal vitamins, I take fish oil as well; it helps with brain development. Also added energy from it helps since I can't just lay down when I feel sleepy.we have 4 children @ home. The ages are 10, 5, 3, & 10 months.
