PLEASE HELP

I've been having cramps and sharp pains in my stomach for the past 3 days. my period was supposed to be yesterday, but it didn't come. sex usually triggers it but not this month. I'm just standing and I'm sweeping and I start sweating. Headaches. Heartburn. Is it possible I'm pregnant? I'm TTC and I took a test the day before my missed period and it was negative. I'm taking one tonight again and one in the morning. Comment 😊
