Hi There, I Have Just Given Birth 3months Ago And

Hi there, i have just given birth 3months ago and its normal delivery. I have 4 front teeth that needs pulling out. A friend of mine who has a dentist friend told me that I cant do tooth extraction until after 6months? Is this true? I am currently part breastfeeding but I can stop the breastfeed for few days while taking antibiotics. My worry is my friend told me that extraction can cause hemorrhage after birth. Please help.
