I had surgery 6 weeks ago, on my wrist and leg. I had my period during the surgery. Is it normal for your period to be late after surgery? should I be concerned? I know stress can really have an effect on your period. and I know I am under alot of stress. Please let me know if its normal to miss or have a delayed period after surgery. I am very regular, to the day normally, so that is why I am concerned. Thank you, I hope you can help.
