Could I be pregnant ?

[YourWaryPinkWriter]

I’m on day 5 of missing my period, I never miss a period it’s always very regular, every 28 days for 5-7 days of bleeding.
I’ve been getting symptoms like nausea and mild cramping. I’m stressing having to wait until a week after my period to get a definitive answer

If your still testing negative then you may just have ovulated late for some reason only mother nature can answer. Your period is based on your ovulation date. I personally was getting a faint line a couple of days before my period was due when I was pregnant, both times, and it was a dark line by the time my period was due. Even with the cheap strips. Hopefully your period will turn up in a day or two.
