Is it true that you should not have pepsi if you're trying to conceive?

Not too sure if pepsi is a culprit but caffeine, which is found in Pepsi/Coke, has been known to make conception difficult. Caffeine stimulates your nervous system, temporarily increasing your heart rate and raising your blood pressure, thus constricting the blood vessels, slowing blood flow to the uterus and potentially making it harder for an egg to attach. Ladies with either fertility problems or above the age of 35 have been known to quit caffeine altogether when trying to conceive.

Pepsi contain caffeine.. if wan try to conceive have to cut down on all caffeine drink..
