Odd period, now puking?

Elizabeth

My period is normally really heavy. As in soak-through-a-super-tampon-in-2-hours. Well, it started 2 days ago, and I've been using light tampons since. It's red blood though, not just pink spotting. This morning I woke up and I'm having "stomach problems" and I'm going to puke. I know it's coming. So I took a test

Negative, right?
