I'm 4-5 days late

Lindsay • 👫💏💖
I am never more than a day late or early. It's driving me crazy! My body is acting wierd, I'm overly emotional, my breasts are killing me during everyday activities! I've never had tender breasts during my periods, only incredibly severe cramps and neusea.
Now I've also taken two early response pregnancy tests, one 4 days before I was supposed to have my period, the second was yesterday, three days after I was supposed to start. Both were negative. It's fully possible that it's stress but I've been under much more intense stress and I've never had it interfere with my period. This is driving me crazy. If I don't get my period by next week I'll try to see my doctor.
