Help!

So my period is super regular. Last month it was 2 weeks late, I relate it to being stressed from moving... Anyway, my husband and I have been TTC and my breasts have been super tender all over, but mostly in the nipples, hungry but nauseated while eating, some cramping and AF hasn't shown her face yet and so it makes it 2 days late. I took a test on Thursday and it was negative. Should I keep waiting or should I take another test??
