Mazal tov on the birth of your baby!
Postpartum bleeding tends to come and go in waves. The median duration is four weeks, which means that 50% of woman will bleed for longer. So you should mentally prepare for the possibility that bleeding will return before you can complete the clean days. At the same time, it is quite possible that you will be able to get through them successfully, so you should not hesitate to try.
A hefsek taharah or bedikah does not need to be completely clear. For example, a light brown (e.g., the color of coffee with milk) with no hint of a reddish tint is not a niddah color and is fully acceptable. Based on your description, it sounds as though you have a good chance of getting a hefsek taharah.
Since the vaginal area is sensitive postpartum, we recommend being careful and gentle with cleaning yourself out and bedikot. it is also permissible to omit the moch dachuk for this cycle.
