This may be a stupid question since I have had three children and should know the signs of pregnancy but this is a new one for me. I stopped nursing my youngest one in October. My milk dried up in November. I was just in the shower and noticed something yellow on my nipple and discovered it was a thick yellow colostrum. It is coming from both breasts. My period is not late yet. I am due to start on January 27th. Any advice will be greatly appreciated :)
