The transfer process is very smooth and most patients do not experience any bleeding or spotting after their transfer however if you do it is nothing to worry about. A reason for some spotting could be because you have a narrow cervical opening. The blood is not coming from your uterus and your embryos are not affected in any way. The tiny drop of blood is not your embryo so you should keep calm and carry on with your everyday activity. In the extremely unlikely event that you experience heavy bleeding after the transfer then you should let us know immediately.
