pregnancy scare

I'm quarantined with my boyfriend of six years. I've been waiting for my period to come for more than a week. I have an IUD, it's unlikely that I'm pregnant but I'm sooo scared. My boyfriend has been so supportive, telling me that we're gonna be okay whatever happens. I love him so much and I want to raise his children some day. But I'm not ready yet. Gonna take a test tomorrow. Wish me luck!
