Could Hot Flushes And Abdominal Cramps Be The Symptoms Of Pregnancy?

hi I m just wondering if I could be pregnant I have been turned of most food for the last week I keep crying one minute then laughing the next I have not been able to sleep for the past 3 days and I m so tired and now for the past 3 days I have these funny little cramp feelings really low in my stomach also my belly does not want to be pulled in it wants to hang forward I feel like most of my body is losing weight and been pushed to the front but I m not due for my period for a week and I also have hot flushes thank you
