raspberry leaf tea and red clover for fertility?

Has anyone heard of this combo? Or one or the other for fertility? I've read that it's supposed to aid it. Also help with heavy or long periods. Which I have. Also I've read it can help strengthen blood flow to ur reproductive organs which can help you keep the pregnancy and lower risk of MC? and also strengthen the uterus for less rush of MC? Just wondering if anyone has used or is using or has a story??
