can I be Pregenat

Me and my husband have been trying to get pregenat for the past two months, my period is regular and I don’t get it until Oct 28. I have been having some symptoms…really bad back pain lower and the middle of my back and also obdominal pain on my left side and going to the washroom more often. I would like to do a pregenany test but they say not to do one until your period is due. Can I be pregenant? If anyone has any helpful answers. Thank you!
