Nauseous ..... Help!?

Joey • Enjoying family, and waiting on my Twinkies to arrive
For the past week I've been feeling nauseous. I don't know if this means I'm pregnant. I'm don't know if I should get my hopes up or just wait. But I want to test. Aunt Flow comes on the 7th or 8th. Before or on my fiancés birthday. Should I wait or test tomorrow? I've been ttc for 8 months now. Help!!!
