Hi, I had gone through your question and understand your concerns.
usually after delivery body has to balance all hormone levels and because
prolactin which is milk producing hormone will cause some changes.
White discharge is called lochia due to cervical part of uterus.
If it is associated with itching ,pain, bad smell then only you should worry about it.
Oral contraceptive pills also cause this, by effect on cervical mucus.
Do not worry it is not due to
pregnancy.
Immediately after delivery natural
contraception will be there because of lctation.
Get a gynic appointment and get a
PAP SMEAR ,it will show any pathology .
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Thank you.
