Postpartum discharge

Sorry this is gross so if you are not wanting to see keep scrolling. Im one month postpartum and was wondering if this is normal. My discharge has turned yellow and i feel like it has a sour cream smell? After the first two weeks i really didnt have much bleeding. We have done “outercourse” along the way. just wanted to make sure it didnt look like an infection of some kind. Thanks! Also i had a second degree tear and peri urethra tear with skid marks.
