Help please..

I've had my iud for over a year and I've never had any symptoms before my period. Me and my so always have unprotected sex and he always finishes in me but these past 2-3 days I've been feeling so sick and nauseous all the time, which is how I felt when I was pregnant with my daughter. But I dont know. My period is supposed to come in 10 days.

Could i possibly be pregnant?
