i had a baby 0n the 17th july, i am exclusively breast feeding although baby goes through the night, between 8-10 hours. on 29th august i had unprotected sex with my husband, althought he pulled out, 7-9 days after i had a very light pink discharge/bleeding? but only when i wiped, i'm also very tired. but i've got a 7week old, 22month old & 5yr old to look after. i stopped bleeding from having baby 4weeks ago & haven't had a period. also that night was the only time i've fancied sex in the last couple of months. Could i b pregnant or is it my cycle trying to sort it out?
