Miscarriage?

So, pretty sure I just had / am having a very early miscarriage.

I had a very very faint faint line last week on a test, but didn’t show up on any more tests... so I kinda chalked it up to an oddity... then..

I was over a week late on my period, along with EXTREMELY painful boobs, consistent nausea around 8:30 at night (weird).

My cycle started yesterday, VERY painful, BRIGHT RED, and continues to be painful even today. When it started yesterday I felt like I was gonna be sick, I woke up dizzy, was incredibly light headed and nauseous, kinda felt like I was gonna topple over at times.

Thoughts?
