TTC Question

Reyna
Hello ladies, My hubby and I have been TTC for 4 months now. I am 5 days late on my period and since I stopped my BC I've been a week late each month so I'm not to excited yet. I have been getting dizzy and feel nauseous at times, should I take a test now or wait after a whole week? Has anybody else felt this way? Any suggestion are welcome! :)
