Pregnant?

I just took out my iud this past week and my husband and I have sex with any protection to avoid a pregnancy. We have a 4 year old together and have been together for 6 years married for almost 2 years. I am suppose to get my period tomorrow but I have a feeling that I am pregnant. Has this situation happened to you or similar? Can you please tell me the outcome weather you were pregnant or not? Thank you.
