In fact， even light or moderate consumption of caffeine — around two to eight cups of coffee daily— increases the risks of problems associated with premature birth by between seven and nine percent， according to a study from April of last year. The study looked at thousands of Danish infants born early. In general， doctors recommend limiting yourself to just one serving every few days when pregnant so make sure your morning cup counts！ If， however ，you are going through menopause ——then you might want to keep having your regular morning java——since caffeine may actually reduce hot flashes！ According to recent animal test results released earlier this month……
