Help. Anyone else?

Has anyone experienced typical period cramps, but received a BFP instead? I’ve been cramping the last 3 days and my period is do tomorrow. I know this is normal PMS for others, but not me. These are period like cramps and I only cramp the day of my period and that’s it. I’m getting really frustrated. If it’s AF, I just need it to show up already because she’s being a little bitch right now.
