So this whole week I been feeling nauseous after every meal and when I wake up, there's also a headache and stomach cramping in my stomach that I've never felt before. I know my period is suppose to come next week but all these symptoms I don't ever get with my period at least not since 2007. My husband and I did have sex on may 5th and this last week has been hard on me feeling nauseous, head hurts, the cramping, dizzy in the morning, and tired all the time. Could that be early signs of me being pregnant?
