Sounds like if you have a fever it could be an infection! If you do have a fever head to the emergency department
No that sounds like one of the symptoms your meant to report ASAP as could be linked to parts of placenta still being inside. Could be nothing but I had early miscarriage and bits stayed inside after and ended up needing to have an operation like a d & c as i was so ill with symptoms like you describe I was lucky not to get blood poisoning from the infection. Check it out soon :)
