8 days is too soon imo
Wait the 6 weeks. They ask you to wait for a reason. No judgement. Feeling great is wonderful and all, but it’s not about how you feel, it’s about your body physically healing inside. Don’t risk it . Get the all clear earlier if you cannot wait! ( see if they will give you the all clear of Course )
Yes every body heals differently, but your uterus didn’t miraculously heal it self in 8 days and your cervix probably hasn’t closed 8days pp. Your cervix wouldn’t be closed and you’d be introducing bacteria in there and as others have stated it’s the wound left from the placenta that can cause an infection. If you had a episiotomy you’ll likely irritate it, it could reopen, and you risk infection from that alone. I’m with the other women saying there’s a reason doctors recommended not putting anything in the vagina for 6-8wks and waiting for your pp checkup. The doctor does a physical vaginal exam and makes sure things have healed properly from the inside and check to make sure your cervix has closed.
You have a dinner plate sized wound inside you from where the placenta detached. You also likely still have episiotomy stitches. I’d strongly advise you relax and let yourself heal.
8 days is way too soon imo. You may feel fine on the outside but remember your insides have essentially have an open wound that is healing.
