Hi there. I am 38 years old and believe I might be pregnant. Most people would probably say it's too early to really know for sure, as I haven't missed my period yet but I've had several symptoms: nausea, dizziness, diarrhea and constipation, lack of appetite and an aching lower back. I'm about a week after conception, or five days past ovulation. This would be my second pregnancy. Do you think these sound like pregnancy symptoms? Thank you so very much for your help.
