Not having very many symptoms, BUT...

My AF was suppose to arrive last Sunday. I am always a little irregular, 2-3 days either way. Well, AF hasn't shown her bloody face yet. I took a test on Tuesday, but it was negative. For the last few weeks though, I have been so tired I can't even keep my eyes open sometimes. Also, I have been throwing up for the past 4 days around the same time every evening. I was just wondering how long I should wait until we test again? The two above are the only symptoms I have (besides being bloated beyond all measure!). We have been anxiously awaiting a BFP For over a year now, so I'm hoping this time it sticks! Any thoughts?
