So I recently had my 6 week post partum check up and my doctor gave me the Depo shot. He told me to use a condom for the first 72 hours if I had intercorse. Well it has been 96 hours (4 days) and me and my husband had intercorse, and he finished inside me without a condom. After this I read online that you should wait 1 week until you can have intercorse without a condom. Is this ttrue? My doctor only said 72 hours, was I protected? Also I am exclusivity best feeding if that has anything to help.
