Dizziness

My husband and I have just started TTC literally just as of last week. However, I have been off of my birth control pill for about two months now. I was told to do so so that it will get out of my system. We have not been trying however, but as we know you can still get pregnant just from the "pulling out" method. I have been feeling extremely tired during the day just recently (I get about 9 hrs of sleep a night) but that could just be because I'm "sleeping too much". Well, today I am feeling very dizzy and disoriented. I just try to lay on the couch and relax so that it will pass but keeps coming back. Could this be an early pregnancy sign ?
