Period 7 weeks PP

My postpartum bleeding stopped for like 3 days before my period started , I haven’t been sore or anything but haven’t had a chance to schedule my postpartum checkup appointment . The bleeding is so bad and I’ve been using pads but I hate it . It feels so gross and I have to change it like every 30 minutes 🙄 would it be okay to use tampons ? I know y’all are gonna say go to the appointment or talk to my OB but that’s not an option right now . Did you use tampons the first period after baby ?
